Description

Technical Field

[0001] This disclosure relates to the field of fine grinding equipment, and more specifically, to equipment for fine grinding of pulp. Background Technology

[0002] Traditional grinding discs are typically manufactured using casting, welding, or milling processes. Casting often results in large grinding discs that require a draft angle to remove from the mold. Furthermore, the draft angle increases the thickness of the ribs, which reduces the cutting edge length and overall surface area of ​​the machined material, ultimately decreasing the efficiency and effectiveness of the grinding process.

[0003] In contrast, milling-manufactured grinding discs can be designed without draft angles, thus achieving the desired cutting edge length with thin or micro-stem features to increase the ground surface area. However, this process requires dense machining of grooves and ribs, which significantly increases machining costs and adds complexity to connecting the grinding discs. This complexity leads to a higher product scrap rate and further increases the cost of the grinding discs.

[0004] Furthermore, in a welded grinding mill disc, the disc consists of multiple components, including ribs, grinding discs, and a base plate. Multiple ribs are constructed together with the grinding discs, and these discs are then assembled onto a single base plate to form the welded grinding mill disc. Constructing multiple ribs within the grinding discs requires forming an equal number of grooves within the discs, necessitating precise machining to ensure a robust and rigid configuration. This precision further increases the machining cost of the grinding discs.

[0005] When the ribs and grooves are irregular or curved, machining becomes more complex, leading to higher processing costs and increased scrap rates. If the grooves are not machined in a single machining setup, manufacturing defects (such as contour inhomogeneity, groove uniformity issues, and disc integrity problems) become more common. Furthermore, the grooves must be machined to form a uniform bottom surface opposite the rib and disc configuration to ensure complete assembly with the substrate.

[0006] The integration of flow limiters into the grinding discs adds further complexity, as separate grooves must be machined into the grinding discs to accommodate the flow limiters, increasing the overall complexity and cost of the grinding discs. Furthermore, the flow limiters must be designed to facilitate smooth and efficient slurry grinding without causing blockages or clogging between the paired grinding discs. Inappropriate design or configuration of the flow limiters increases the grinding load, leading to higher power consumption and a shortened grinding disc lifespan.

[0007] In another embodiment, precise grooves must be machined for the flow restrictor according to the pulp flow passing through the refiner disc. This further increases processing time, scrap rate, and profile complexity, significantly increasing the manufacturing cost of the welded refiner disc with the flow restrictor. If poorly designed, the flow restrictor can lead to unexpected refiner loads or blockages, thereby reducing the efficiency of pulp refinement and the overall papermaking process and increasing costs.

[0008] Therefore, there is a technological gap that needs to be addressed by developing an effective manufacturing method for the grinding disc. Summary of the Invention

[0075] Detailed Implementation

[0076] This invention relates to a grinding mill disc used for papermaking and grinding of lignocellulose and other natural / synthetic fiber materials in the manufacture of paper, paperboard, fiberboard, molded fiber, and other related products. In particular, this invention relates to a method for manufacturing a single-set grinding mill disc and the grinding mill disc manufactured by this method.

[0077] Figure 1 A homogeneous type grinding mill disc (100) is shown, comprising a plurality of grooves (102) connected to a surface (103) of the disc (100). These grooves (102) extend horizontally along a length (Y) on the surface (103) of the disc (100). The grooves (102) are manufactured with parallel profiles, forming a series of narrow channels. Processing tools selected from, but not limited to, drilling machines, CNC machines, laser operations including but not limited to, laser cutting, laser drilling, wire cutting, etc., or combinations thereof, pass through these channels. The disc (100) has a complex pattern of grooves (102) radiating outwards from the center of the disc (100) to its edges. Furthermore, as... Figure 1 As shown, the groove (102) includes an outlet groove (101), wherein each of the outlet grooves (101) can be bridged by an outlet groove (101) between two consecutive grooves (102). The arrangement of the outlet grooves (101) allows the machining tool to move continuously to form the next groove without interruption after forming one groove (102). This design ensures that the tool does not need to stop during the groove formation process. The outlet grooves (101) between two grooves (102) can be arranged in a zigzag or alternating pattern. A single outlet groove (101) must be formed between every two grooves (102). In particular, in the Figure 1The diagram shows two exit grooves (101) arranged between three grooves (102), wherein one exit groove (101) is positioned at a predetermined distance (D) from the other exit groove. This specific arrangement allows for precise control of the movement of the machining tool between the grooves, thereby ensuring the uniformity and efficiency of the groove formation process. The exit grooves (101) ensure that the tool moves consistently from one groove (102) to the next, thus maintaining the same depth of cut and shape throughout the process. This prevents variations that may occur when the tool stops and starts unevenly. The stepped rise and step fall pattern, zigzag pattern, or alternating pattern of the exit grooves (101) can be used to control the relative position of each groove (102), thereby ensuring that the grooves are evenly spaced and aligned. This precision ensures that all grooves are evenly distributed on the disc (100). However, after all the grooves (102) and the outlet groove (101) are formed, ribs (104) are constructed in the grooves (102) and flow restrictors (105) are constructed in the outlet groove (101).

[0078] In an embodiment, such as Figure 2 As shown, the grinding disc (200) can be constructed by forming multiple sectors (207) of the same or similar type, wherein each sector (207) comprises multiple parts, and each sector includes, but is not limited to, multiple ribs (204) constructed together with the grinding disc (205). The construction of the ribs (204) and the grinding disc (205) can be integrated with the substrate (300), such as... Figure 3 As shown in Figure 19, the rib (204) extends vertically to achieve a length (X) at the top, such that the rib (204) is confined within the groove (202) formed on the surface (203) of the grinding disc (205). The rib (204) extends vertically upward from the groove (202) in a direction perpendicular to the surface (203), and the rib is a distance (X) from the grinding disc (205). Additionally, the rib (204) extends horizontally along the groove (201) of the grinding disc (205) for a length (Y) (as shown in Figure 19).

[0079] In addition, such as Figure 2As shown, the grinding mill disc (200) includes a plurality of segments (208) of the same or similar type configured to be assembled to each other via locking members (206), and the segments (208) may be configured with a plurality of sectors (207) to complete the disc (200). In one embodiment, the segment (208) may include at least two sectors (207) to assemble the segment (208) and the substrate (300) to each other to construct the disc (200). However, the outlet groove (201) is manufactured using a one-time setup method to facilitate the construction of a flow limiter.

[0080] In an embodiment, Figure 3 A substrate (300) is shown, wherein the substrate (300) of the grinding mill disc (200) provides options for fixing the grinding disc (205) using techniques including but not limited to fastening, welding, interlocking, etc. Figure 3 An alternative method for securing the grinding disc (205) to the substrate (300) by welding (301) is introduced. In this invention, the welding is performed in such a way that the grinding disc (205) is welded to the substrate (300) only at specific points to ensure a robust configuration, without welding the entire surface, which could adversely affect the mechanical properties of the component by creating a very wide heat-affected zone. This method is particularly useful when minimal movement is required to secure the grinding disc (205) in place, or when a single mechanical locking mechanism may not provide sufficient security. Figure 3 The image shows a rear view of the substrate (300), illustrating the location of the weld seam. The grinding disc may initially be positioned on the substrate (300) using primary mechanical alignment (such as dovetail or plug-and-slot locking), followed by welding at critical points. The welding process involves applying pressure and heat to specific points, melting the metal at the contact point, and forming a strong bond as the metal cools and solidifies. Using welding offers several advantages:

[0081] 1. Strong connection: Welding creates a very strong connection between the grinding disc (205) and the rib (204) configuration and the substrate (300), which is critical in high-stress environments such as pulp milling.

[0082] 2. Reduced material stress: Since welding is performed only at specific points, there is less overall thermal deformation and stress on the grinding disc (205) and the rib (204) configuration and the substrate (300) compared to full-surface welding that gives the grinding disc (205) and the substrate (300) a robust configuration.

[0083] 3. Precise arrangement: Welding enables precise arrangement of the configuration of the grinding disc (205) and the rib (204), thereby ensuring that the grinding disc and the rib remain perfectly aligned during the fine grinding process.

[0084] In an embodiment, Figure 4 A disc (400) is shown, comprising a plurality of grooves (401) formed on a grinding disc (403), wherein exit grooves (402) may be connected between the grooves (401) to form a smooth transition for machining tools or a path for laser-operated cutting or trimming between the grooves (401). Furthermore, the plurality of exit grooves (402) between the grooves (401) may be constructed in a manner forming a plurality of spiral grooves. The plurality of grooves (401) may be configured to be spaced apart to form ribs (404) within the grooves (401) followed by the formation of channels or valleys (403) between the grooves (401). The exit grooves (402) may be arranged in a zigzag or alternating pattern. In particular, it is necessary to form a single exit groove between every two grooves.

[0085] In an embodiment, Figures 5 to 7 The versatility and importance of the various locking mechanisms in the components of the grinding mill discs (200, 400) are illustrated. These locking mechanisms are crucial for maintaining the structural integrity of the grinding mill discs (200, 400), especially during the manufacturing and assembly of the grinding discs (503, 603, 703). Figure 5 A locking mechanism of the type of plug (501) and socket (502) is shown, which is one of the most direct and effective methods for securing grinding discs (503) together. In this mechanism, one grinding disc (503) is equipped with a protruding "plug (501)," while adjacent grinding discs (503) have corresponding "sockets (502)" or "recesses (502)" designed to receive the plug (501). When the grinding discs (503) are arranged adjacent to each other, the plug (501) fits tightly into the socket (502), thereby effectively locking the grinding discs (503) together.

[0086] Figure 6 It shows something similar to Figure 5 An embodiment of the locking mechanism is shown. In this mechanism, each grinding disc (603) is equipped with a protruding "plug (601)," while adjacent grinding discs (603) have corresponding "holes or recesses (602)" designed to receive the plugs (601). When the grinding discs (603) are arranged adjacent to each other, the plugs (601) fit tightly into the holes (602), thereby effectively locking the grinding discs (603) together. However, in Figure 6In the middle, the shape of the protruding plug (601) can be, but is not limited to, pentagonal, hexagonal, trapezoidal, or dovetail shapes, and such Figure 5 The shape of the protruding plug (501) shown can be, but is not limited to, rectangular, square, or U-shaped. Furthermore, in Figure 7 In this design, the protruding plug (701) can be of various shapes, including but not limited to elliptical, semi-circular, curved, or circular. These different configurations of the plugs (501, 601, 701) can be used in a variety of locking mechanisms, thereby enhancing the versatility and application of the grinding discs (503, 603, 703). Accordingly, the sockets (602, 502, 702) are designed to match the shape of the corresponding plugs (501, 601, 701) of the sockets, thereby ensuring a secure and precise fit for each configuration.

[0087] Figures 5 to 7An excellent pattern of grooves (505, 605, 705) is shown, wherein each groove in the grooves (505, 605, 705) is evenly spaced and extends parallel to the length of the grinding disc (503, 603, 703) to perform uniform fine grinding of the input material. The machining tool can enter the grinding disc (503, 603, 703) to perform a drilling operation on the grooves (604, 504, 704, 505, 605, 705) starting from the inlet groove (505b, 605b, 705b), the inlet groove (505b, 605b, 705b) being positioned relative to any one of the edges (507, 607, 707) and / or the sectors (506a, 606b, 706f) of the grinding disc (503, 603, 703), wherein the machining tool breaks the edges (507, 607, 707) to create a first groove, the first groove being referred to as the inlet groove (505b, 605b, 705b) of the edge (507, 607, 707). Furthermore, the machining operation continues without removing or lifting the tool from the grooves (604, 504, 704, 505, 605, 705) until all the required grooves (604, 504, 704, 505, 605, 705) are machined on the grinding discs (503, 603, 703) and / or the sectors (506a, 606b, 706f). Furthermore, when the grooves (505, 605, 705) are divided into two or more groups or sectors (506a, 506b, 606a, 606b, 706a, 706b, 706c, 706d, 706e, 706f) to form the grinding discs (503, 603, 703) and / or specific rib patterns that facilitate material flow in order to achieve a specific fine grinding effect on the input material with lower power consumption, the groups or sectors (506a, 506b, 606a, 606b, 706a, 706b, 706c, 706) d, 706e, 706f) can be constructed to each other in such a way that at least one end groove (505a, 605a, 705a) is formed on the edge opposite to the edge (507, 607, 705b) where the inlet groove (505b, 605b, 705b) is provided, the end groove (505a, 606a, 706a) leading to the corresponding group or sector (506a, 506b, 606a, 606b, 706a, 706b, 706c, 706d, 706e, 706f). In an exemplary embodiment, the end groove (505a) is formed in the sector (506b) and leads to the corresponding sector (506a), while the end groove (605a) is formed in the sector (606a) and leads to the corresponding sector (606b).In another exemplary embodiment, the end groove (705a) is configured into a plurality of sectors (706a, 706b, 706c, 706d, 706e, 706f), wherein the end groove (705a) enables the sectors (706a, 706b, 706c, 706d, 706e, 706f) to be configured with each other by means of corresponding sectors (706b, 706c, 706d, 706e, 706f), for example, The groove (705a) of sector (706a) leads to sector (706b), the groove (705a) of sector (706b) leads to sector (706c), the groove (705a) of sector (706c) leads to sector (706d), the groove (705a) of sector (706d) leads to sector (706e), and the groove (705a) of sector (706e) leads to sector (706f). The end grooves (505a, 605a, 705a) lead to the corresponding sectors (506a, 506b, 606a, 606b, 706a, 706b, 706c, 706d, 706e, 706f), ensuring continuous processing of the sectors (506a, 506b, 606a, 606b, 706a, 706b, 706c, 706d, 706e, 706f). This allows for the manufacture of complete grinding discs (503, 603, 703) in a single, error-free setup without removing the processing tools, thereby improving processing efficiency. Furthermore, at the junctions of the sectors (506a, 506b, 606a, 606b, 706a, 706b, 706c, 706d, 706e, 706f), a gap separate from the end grooves (505b, 605b, 705b) can be maintained to allow smoothing material and steam to flow over the polished surface. However, outlet grooves (504, 604, 704) can be formed within the sectors (506a, 506b, 606a, 606b, 706a, 706b, 706c, 706d, 706e, 706f) to serve as connectors between the parallel grooves (505, 605, 705), thereby achieving flexibility and mobility. The outlet grooves (504, 604, 704) are arranged in a radial pattern from the center of the semicircular sector toward the edge of the grinding disc (503, 603, 703). However, the grinding disc (503, 603, 703) allows the outlet grooves (504, 604, 704) to act as connectors between the parallel grooves (505, 605, 705) within each sector (506a, 506b, 606a, 606b, 706a, 706b, 706c, 706d, 706e, 706f). Furthermore, the outlet grooves (504, 604, 704) bridge the gap between two parallel grooves (505, 605, 705).This bridging is crucial for maintaining the structural integrity of the grinding discs (503, 603, 703) to enable cost-effective and error-free manufacturing of the grinding discs (603, 603, 703), while achieving a smooth construction of the current limiter.

[0088] In particular, Figures 5 to 7 The machining process of forming the multiple grooves (504, 604, 704) in a bending manner is illustrated. The key innovation lies in the continuous path of the machining tool, eliminating the need for tool retraction, deployment, and repositioning between each groove (505, 605, 705). This is achieved through the design of "exit grooves" (504, 604, 704), which allow the machining tool to smoothly transition from one groove (505, 605, 705) to the next without interrupting the cutting process. This continuous path optimizes machining efficiency by reducing downtime, minimizing tool wear, and ensuring consistent groove (505, 605, 705) forming, while also allowing the flow restrictor to be smoothly constructed within the exit grooves (504, 604, 704).

[0089] In an embodiment, Figure 8 and Figure 9 Different aspects of the fine grinding mill plate sections via dual mounting (803) and single mounting (903) are shown respectively. The figures disclose a grinding disc (801, 901) comprising at least one sector (801a, 901a). The sectors (801a, 901a) can be configured according to... Figures 2 to 7 The assembly of the grooves (802, 902) integrated into the grinding discs (801, 901) of any embodiment shown. The configuration of the grooves (802, 902) and the grinding discs (801, 901) can be mounted to a fine grinding mill mounting device (not shown) using various fastening methods, including but not limited to fastener joints, riveting joints, or other types of mechanical joints.

[0090] In an embodiment, Figure 10 Various configurations of the grooves (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) and the outlet grooves (1001a, 1001b, 1001c, 1001d, 1001e, 1001f, 1001g) are shown. Figure 10 a to Figure 10g). Grooves (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) formed on the surface of the grinding disc (100) or the grinding wheel (205, 503, 603, 703, 801, 901) can be constructed to each other to form the grinding disc (200, 400, 2000, 2100, 2200) and extend horizontally and / or at an angle. These grooves (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) are arranged in parallel lines to form a series of narrow channels (1001ab, 1001bb, 1001cb, 1001db, 1001eb, 1001fb, 1001gb) to provide space for material flow along the finely ground surface. The grooves (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) and the outlet grooves (1001a, 1001b, 1001c, 1001d, 1001e, 1001f, 1001g) are carefully designed with uniform width and depth to ensure precise material removal during the fine grinding process. In one embodiment, the grooves (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) and the outlet grooves (1001a, 1001b, 1001c, 1001d, 1001e, 1001f, 1001g) in the case of a single-piece or homogeneous type of grinding disc (100) may have local depths, and the single-piece or homogeneous type of grinding disc may be configured such that the ribs (104) can be assembled on top, while in another embodiment, in the manufacture of multiple sectors (207, 801a, 901a) and / or having the grinding discs (205, 503, 60... In the case of a fine grinding disc (200, 400, 2000, 2100, 2200) constructed from the sections (208) of 3, 703, 801, 901), the grooves (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) and the outlet grooves (1001a, 1001b, 1001c, 1001d, 1001e, 1001f, 1001g) can be made through the depth of the grinding disc (205, 503, 603, 703, 801, 901) to achieve a top and / or bottom-to-top configuration of the ribs (204, 404).However, in the manufacture of grinding mill discs (200, 400, 2000, 2100, 2200), it is mandatory to create the grooves (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) on the surface of the grinding mill disc (100) or the grinding discs (205, 503, 603, 703, 801, 901) to achieve the relationship between the ribs (104, 204, 404) and the surface (103) of the grinding discs (205, 503, 603, 703, 801, 901) and / or the surface (103) of the grinding mill disc (100). The robust configuration of the grooves (102) facilitates a uniform distribution of force when the discs (100, 200, 400, 2000, 2100, 2200) rotate during operation, which improves the finishing efficiency of the discs (100, 200, 400, 2000, 2100, 2200). The outlet grooves (1001a, 1001b, 1001c, 1001d, 1001e, 1001f, 1001g) enable the construction of flow restrictors to increase the retention of finishing material, thereby improving the finishing efficiency of the discs (100, 200, 400, 2000, 2100, 2200).

[0091] Furthermore, the outlet grooves (1001a, 1001b, 1001c, 1001d, 1001e, 1001f, 1001g) serve as transition paths between consecutive grooves (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) that effectively “bridge” two adjacent grooves (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga). The pattern and alignment of the exit grooves (1001a, 1001b, 1001c, 1001d, 1001e, 1001f, 1001g) are crucial to the machining process because they allow the machining tool to seamlessly move from one groove (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) to the next without stopping or repositioning. The exit grooves (1001a, 1001b, 1001c, 1001d, 1001e, 1001f, 1001g) are arranged to form a continuous path for the machining tool, whether it is a CNC machine, laser drilling or cutting equipment, or wire EDM equipment. This continuous design ensures that after forming one groove (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga), the tool can move smoothly to form the next groove (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga). This seamless advance minimizes tool wear, reduces downtime, and increases the overall efficiency of the groove (1001a, 1001b, 1001c, 1001d, 1001e, 1001f, 1001g, 1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) formation process, thereby increasing the output of the finishing mill discs (100, 200, 400, 2000, 2100, 2200) at a lower manufacturing cost.

[0092] The following is for Figure 10 a to Figure 10 A separate explanation of each configuration of the arrangement of the outlet grooves (1001a, 1001b, 1001c, 1001d, 1001e, 1001f, 1001g) between the vertical grooves (1001aa, 1001ba, 1001ca, 1001da, 1001ea, 1001fa, 1001ga) shown in g:

[0093] Figure 10a: In this configuration, the exit groove (1001a) is manufactured in a parallel groove (1001aa) extending along the surface. The exit groove (1001a) is positioned between two consecutive vertical grooves (1001aa). This configuration emphasizes a simple, direct connection between the grooves (1001aa), allowing the machining tool to travel in a straight line from one vertical groove (1001aa) to the next. The alignment of the exit groove (1001a) ensures minimal deviation, resulting in a smooth and efficient tool transition without interrupting the machining process.

[0094] Figure 10 b: In this figure, the grooves (1001ba) maintain the same parallel vertical alignment, but the exit groove (1001b) is slightly offset between two adjacent vertical grooves (1001ba). This offset design allows the tool to exit one groove (1001ba) and enter the next groove (1001ba) at a small angle, thus providing flexibility in tool movement. This arrangement is suitable for machining processes where slight angular movement is preferred, thereby achieving a smooth transition with minimal tool repositioning.

[0095] Figure 10 c: This configuration illustrates a variation in which the grooves (1001ca) are positioned closer together, resulting in a denser arrangement or bent-rod configuration of the grooves (1001ca) required to achieve the desired finishing effect for a specific application. The exit groove (1001c) can be designed with a concave shape, curving inward between two consecutive vertical grooves (1001ca), which is ideal for applications with limited space where the grooves (1001ca) need to be tightly packed or designed in a curved manner. This design ensures continuous tool movement while still allowing the machining tool to travel efficiently between closely spaced or curved grooves (1001ca).

[0096] Figure 10 d: Furthermore, the grooves (1001da) remain vertically aligned, but the exit groove (1001d) has a convex shape, curving outwards between adjacent vertical grooves (1001da). This convex design ensures that the machining tool travels along an outwardly curved path, thus providing a wider exit route before moving into the next groove (1001da). This configuration is suitable for situations requiring wider or more open transitions between grooves (1001da) to ensure uninterrupted machining.

[0097] Figure 10e: In this configuration, the exit groove (1001e) is slightly angled between the vertical grooves (1001ea). This design allows the tool to move diagonally as it exits one groove (1001ea) and enters another. This configuration is useful in machining processes that require variable angles between the grooves (1001ea), enabling more complex disc patterns and different machining strategies.

[0098] Figure 10 Figure f illustrates an arrangement in which multiple grooves (1001fa) intersect with a series of exit grooves (1001f) to form a continuous pattern. The exit grooves (1001f) are characterized by a wavy or curved shape in the middle and act as inclined or angled bridging elements, thus providing multiple options for tool exit. In this figure, the grooves are also constructed along inclined or angled directions. This arrangement is particularly useful when the tool needs to transition quickly and continuously between multiple grooves (1001fa), thereby maintaining efficiency and minimizing unnecessary downtime or delays.

[0099] Figure 10 g: In this figure, the grooves (1001ga) are more widely spaced, and the exit groove (1001g) has an undulating shape, characterized by a wavy or curved shape starting from the middle. This undulation provides a dynamic transition path for the machining tool, allowing it to follow more complex paths between two consecutive grooves (1001ga). Furthermore, the exit groove (1001g) is positioned at an acute angle, ensuring that the machining tool exits one groove (1001ga) and transitions to the next in a precise and efficient manner. This acute-angled undulation design is particularly useful in accommodating more complex groove (1001ga) transitions while maintaining continuous tool movement.

[0100] In another embodiment, Figure 11The configuration of a flow restrictor (1101) is shown, wherein the flow restrictor (1101) can be inserted into an outlet groove (1100) formed between ribs (1102) on the grinding disc (1103) and protrudes between two adjacent ribs (1102). The flow restrictor (1101) serves a dual purpose: it reinforces the configuration of the grinding disc (1103) and the ribs (1102) and also controls the material flow between the ribs, thereby increasing the material retention time and improving the finishing quality. Specifically, the flow restrictor (1101) is inserted from the bottom of the grinding disc and extends upward to the top surface, wherein the flow restrictor is confined in the outlet groove (1100) formed on the grinding disc (1103) between the ribs (1102) in such a way as to completely or at least partially block the channel (1104) to reinforce the configuration of the grinding disc (1103) and the ribs (1102), and the blockage of the channel (1104) increases the material retention time and improves the finishing quality to enhance the finishing process by controlling the pulp flow through the finishing mill discs (100, 200, 400, 2000, 2100, 2200).

[0101] In an embodiment, Figure 12 (ad) shows the corresponding Figure 10 a, Figure 10 b、 Figure 10 c and Figure 10 Different configurations of the current limiter (1100) (e.g.)

[0102] Figure 12 a: In this configuration, the flow restrictor is angled along its diagonal, thus forming an inclined structure extending between two adjacent grooves (1001ba) of the outlet groove (1001b). This diagonal design helps to restrict the material flow at an angle, effectively increasing resistance and retention time when the material flows between the grooves (1001ba). This diagonal design corresponds to Figure 10 b, in Figure 10 In b, the grooves (1001ba) are arranged in parallel, and the outlet groove (1001b) is tilted and aligned so that the tool can move continuously.

[0103] Figure 12 b: This figure illustrates a concave flow restrictor that bends inward to form a semi-circular shape between adjacent grooves (1001ca). The concave shape enables controlled, smooth material flow while still increasing the material retention time within the grooves (1001ca). The bent shape also increases the structural strength of the flow restrictor, making it more wear-resistant over time. This configuration corresponds to Figure 10 c, in Figure 10In c, the outlet groove (1001c) provides a curved and compact transition between the continuous grooves (1001ca).

[0104] Figure 12 c: Here, the flow restrictor exhibits a similar convex shape, but on a smaller scale with a smaller curvature. This design is particularly effective in maintaining stable flow restriction while allowing material to pass through more efficiently, maintaining a balance between flow control and retention. This configuration corresponds to Figure 10 d, in Figure 10 In d, the grooves (1001da) are more closely spaced, and the outlet groove (1001d) has a compact design. The smaller, more compact flow limiter shape fits well with the more compact groove arrangement.

[0105] Figure 10 The concave flow limiter disclosed in b will create a depression that can hold more pulp and increase retention time, while Figure 10 The convex design flow limiter disclosed in c will produce a more aggressive flow-limiting protrusion, thereby potentially enhancing the grinding effect.

[0106] Figure 12 d: In this configuration, the flow restrictor is undulating, with multiple peaks and valleys, giving it a wavy or sawtooth appearance. This complex shape maximizes material retention and flow control by creating multiple resistance points between adjacent ribs. This complex shape corresponds to Figures (10e-g), where the grooves and outlet grooves (1001e, 1001f, 1001g) form a more complex and variable pattern. The undulating flow restrictor design is well-suited for situations requiring more complex flow control and increased finely ground surface area.

[0107] In an embodiment, Figure 13The diagram shows an interlaced pattern of outlet grooves (1302) connected to the surface of the grinding disc (1303). The arrangement of the grooves (1301) appears to consist of parallel grooves (1301) with outlet grooves (also referred to as transverse grooves) (1302) between them. Furthermore, the parallel grooves (1301) are spaced at regular intervals, typically several feet apart. On the other hand, the outlet grooves (1302) are perpendicular to the parallel grooves (1301) and are spaced at smaller intervals compared to the parallel grooves (1301). The outlet grooves (1302) form an interlaced pattern by being offset from each other. Specifically, an outlet groove (1302) located on one side of a parallel groove (1301) is not directly opposite an outlet groove (1302) located on the other side of an adjacent parallel groove (1301). First, the outlet groove (1302) follows a continuous descending trajectory from the edge (1304) of the grinding disc (1303) to the center (1305), stabilizing at the center (1305) by means of at least one straight outlet groove (1302). Then, the pattern of the outlet groove (1302) follows an ascending trajectory from the center (1305) of the grinding disc (1303) to the opposite edge (1304), forming a V-shaped pattern of the outlet groove (1302), wherein the central straight groove (1302) traverses the center (1305). However, each outlet groove (1302) is offset from the outlet groove below or above it by approximately half the width of the groove (1301). This produces an interlaced or zigzag pattern, wherein each outlet groove (1302) is not directly aligned with the outlet groove above or below it. Furthermore, the pattern of the outlet groove (1302) facilitates smooth fine grinding without blocking or clogging the material in the adjacent area generated during processing, i.e., the fine grinding material between the fine grinding discs, after the ribs are constructed in the groove (1301) and the flow restrictor is constructed in the outlet groove (1302).

[0108] In an embodiment, Figure 14 A V-shaped outlet groove (1401) pattern is shown without the straight groove (1302) at the center (1305) to provide a distinct material retention effect for performing a balanced finishing process. However, the V-shaped outlet groove (1401) can be offset from the outlet groove below or above the V-shaped outlet groove by approximately half the width of the groove (1301). This produces an interlaced or zigzag pattern in which each V-shaped outlet groove (1401) is not directly aligned with the outlet groove above or below it.

[0109] In an embodiment, Figure 15A grinding disc (1503) is shown having at least two sectors (1500a, 1500b) with a complex groove pattern (1502). The sectors (1500b) can be angled relative to the sector (1500a) to provide different finishing patterns from the two sectors (1500a, 1500b) connected to a single grinding disc (1503). In one embodiment, the tilt angle of the sector (1500b) can be less than 45°, preferably in the range of 2° to 40°. However, the sector (1500a) can be constructed together with the sector (1500b) by means of an outlet groove (1501), which is constructed together with an end groove (1502a) of the sector (1500a) and a first groove or inlet groove (1502b) of the sector (1500b). The grooves (1502) are arranged in a systematic, parallel manner, radiating from the inner edge of the sector to the outer edge, so as to perform a uniform, application-specific grinding pattern on the grinding disc.

[0110] In an embodiment, Figure 16 A grinding disc (1603) constructed with angled sectors (1600a, 1600b) is shown, which does not have the outlet grooves (1501) constructed for the sectors (1600a) and (1600b). The configuration of the sectors without the flow restrictor configuration or the outlet grooves (1501) facilitates a streamlined material flow channel (1604) to provide high material flow in specific applications requiring high material flow. Furthermore, the pattern consists of a series of evenly spaced parallel grooves (1602) with uniform width and depth, cut into the surface of the sectors (1600a, 1600b), with smaller outlet grooves (1601) positioned between each pair of grooves (1602) to connect them. The outlet grooves (1601) are also evenly spaced and have uniform width and depth.

[0111] In an embodiment, Figure 17A cross-sectional view is shown of a rib (1701) configuration constructed together with a grinding disc (1702), wherein the rib (1701) can be constructed together with the grinding disc (1703) such that the rib (1701) can be precisely positioned above a groove (1702) formed on the grinding disc (1703) by means of the slots (1701a, 1701b), and the rib (1701) is gently pushed into the groove (1702) by means of external force or pressure to press-fit the rib (1701) into the groove (1702) having a length (Z), the rib (1701) having a length (Y) formed by the slots (1701a, 1701b). The rib (1701) can penetrate into the groove (1702) at a height (P) formed by the slots (1701a, 1701b) and a depth (Q) into the groove (1702) to lock the rib (1701) within the groove (1702), restricting all degrees of freedom and movement. This creates a rigid and robust configuration of the rib (1701) and the grinding disc (1703), thereby enabling the fine grinding of the raw material input to be performed by means of the length (X) of the fine grinding disc (200, 400, 2000, 2100, 2200). In one embodiment, the configuration of inserting the rib (1701) into the groove (1702) at the height (P) protects the rib (1702) from vertical or horizontal sliding. In another embodiment, the length (Z) of the opening of the groove (1702) or the opening of the groove (1702) may be equal to or slightly greater than the length (Y) of the rib (1701) to achieve a press fit or tight fit between the rib (1701) and the groove (1702). However, the height (P) and the depth (Q) may be equal in size, or the depth (Q) may be greater than the height (P) of the slots (1701a, 1701b). In the case of the grinding discs (200, 400, 2000, 2100, 2200), the groove (1702) can penetrate the grinding disc (1703) so that the configuration of the rib (1701) and the grinding disc (1703) facilitates the formation of a smooth and streamlined surface (which is opposite to the configuration of the rib (1702) and the grinding disc (1703) and / or to a protrusion of the length (X) protruding from the groove (1702) of the grinding disc (1703)), so that the substrate (300) can be uniformly constructed by the configuration of the grinding disc (1703), and in the case of the grinding disc (100), the groove (1702) can be deep enough to accommodate the height (P) of the rib (1702).

[0112] In an embodiment, Figure 18A rib (1801) with a locator (1802) is shown, the locator (1802) being connected within the rib (1801) such that the expandable current limiter shown in FIG. 19(i) can be constructed within the locator (1802) of the rib (1801). The locator (1802) can have different shapes, such as semicircular, semirectangular, or semisquare. The locator (1802) is constructed to the rib (1801) and matches the surface of the grinding disc. The locator (1802) allows the current limiter to be constructed via a top configuration without insertion from the bottom of the grinding discs (403, 503, 603). The top configuration of the locator (1802) has several advantages, including, but not limited to, easy replacement of the current limiter without removing the grinding discs (403, 503, 603), and easy and quick assembly and / or disassembly.

[0113] In an embodiment, Figure 19 illustrates various configurations of the flow restrictor (1900). The flow restrictor (1900) is inserted into the outlet grooves (101, 201, 402, 504, 604, 704, 1001a to 1001g) formed on the grinding discs or surfaces (103, 203, 403, 503, 603) to restrict the flow of the input material into the space between the ribs (104, 204, 404) constructed together with the grooves (102, 202, 405, 505, 605, 705), thereby giving the input material a measured flow rate. The flow restrictor (1100) serves a dual purpose: it helps to lock together with the grinding discs (203, 203, 403, 503, 603) to enhance the configuration of the grinding discs (203, 203, 403, 503, 603) and / or with the ribs (104, 204, 404), and also controls the material flow between the ribs (104, 204, 404) to enhance the finishing quality, thereby increasing the material retention time and improving the finishing quality. Specifically, the flow restrictor (1100) is inserted from the bottom of the grinding discs (203, 203, 403, 503, 603) and extends upwards to the top surface, where it locks the grinding discs (203, 203, 403, 503, 603) into place. This method is used not only for fixed grinding discs (203, 203, 403, 503, 603), but also to enhance the finishing process by controlling the pulp flow through the finishing mill discs (200, 400, 2000, 2100, 2200).

[0114] Figure 19a(a) illustrates a flow restrictor (1900a) with a cross-sectional shape including but not limited to a circle, square, rectangle, pentagon, hexagon, octagon, etc. Furthermore, the flow restrictor (1900a) is inserted from the top or bottom of the grinding discs (203, 403, 503, 603) into the outlet grooves (101, 201, 402, 504, 604, 704, 1001a to 1001g), extending upwards to the top surface between the ribs (104, 204, 404) constructed together with the grooves (202, 405, 505, 605, 705). Additionally, the flow restrictor (1900a) includes a uniform diameter spanning its length and can be constructed from the top or bottom of the grinding discs (203, 403, 503, 603). In a preferred embodiment, the cross-section of the current limiter (1900a) may be circular when viewed from the side, and the shape of the current limiter (1900a) may be cylindrical. This design allows the current limiter (1900a) to fit tightly into the grinding discs (203, 403, 503, 603) to create a strong and waterproof seal.

[0115] Figure 19a (b, c): Complete flow restrictors (1900b and 1900c) are shown, which can be constructed from the bottom of the grinding discs (203, 403, 503, 603) to form a configuration with the grinding discs (203, 403, 503, 603) to provide complete local obstruction to the material flow in the space between the ribs (104, 204, 404). The flow restrictors (1900b and 1900c) include partial or peripheral notches (1900ba, 1900ca) to lock the flow restrictors (1900b and 1900c) together with the grinding discs (203, 403, 503, 603) at the bottom or on the side opposite to the protruding surface of the grinding discs (203, 403, 503, 603) to form a robust and rigid configuration of the flow restrictors (1900b and 1900c) and the grinding discs (200, 300, 400, 2000, 2100, 2000). However, the shape of the current limiter notch (1900ba and 1900ca) can be, but is not limited to, semi-circular, square, rectangular, oval, elliptical, etc., while the cross-section and overall shape of the current limiter (1900b and 1900c) are consistent with those of the current limiter (1900a).

[0116] Figure 19a(d, e, f): Complete flow restrictors (1900d, 1900e, and 1900f) are shown, which can be constructed from the bottom of the grinding discs (203, 403, 503, 603) to form a configuration with the grinding discs (203, 403, 503, 603) to provide partial complete obstruction to the flow in the configuration space between the ribs (104, 204, 404). The flow restrictors (1900d, 1900e, and 1900f) include bottom extensions (1900da, 1900ea, and 1900fa) instead of the partial or peripheral notches (1900ba, 1900ca) to lock the flow restrictors (1900d, 1900e, and 1900f) below the grinding discs (203, 403, 503, 603, and 703), while limiting the bottom extensions between the grinding discs (203, 403, 503, and 603) and the substrate (300), to form a robust and rigid configuration of the flow restrictors (1900d, 1900e, and 1900f) and the grinding discs (200, 300, 400, 2000, 2100, and 2200). However, the shape of the bottom extensions (1900da, 1900ea, and 1900fa) can be, but is not limited to, semi-circular, square, rectangular, oval, elliptical, etc. The bottom extensions extend beyond the diameter cross-section of the top side (1900db, 1900eb, and 1900fb) of the current limiters (1900d, 1900e, and 1900f), while the cross-section of the top side (1900db, 1900eb, and 1900fb) of the current limiters (1900d, 1900e, and 1900f) is consistent with that of the current limiter (1900a).

[0117] Figure 19a (g, h, i, j) and Figure 19bPartial current limiters (1900g, 1900h, 1900i, 1900j and 1900k) are shown, which can be constructed from the bottom of the grinding discs (203, 403, 503, 603) to form a configuration with the grinding discs (203, 403, 503, 603). The flow restrictors (1900g, 1900h, 1900i, 1900j, and 1900k) include flow outlets (1900ga, 1900ha, 1900ia, 1900ja, and 1900ka) on any side of the outer periphery of the flow restrictors (1900g, 1900h, 1900i, 1900j, and 1900k) to allow a portion of the material flow to pass through the flow restrictors (1900g, 1900h, 1900i, 1900j, and 1900k) in the space between the ribs (104, 204, 404) to prevent material blockage between the pair of grinding mill discs (100, 200, 400, 2000, 2100, 2200) during the operation or grinding action of the grinding mill. In this context, based on any of the previously mentioned flow restrictors (1900a to 1900f) and the grinding discs (200, 300, 400, 2000, 2100, 2200), the flow restrictors (1900g, 1900h, 1900i, 1900j, and 1900k) can be constructed together with the grinding discs (203, 403, 503, 603, and 703). However, the drain sections (1900ga, 1900ha, 1900ia, 1900ja, and 1900ka) can be of a type designed according to application requirements, including but not limited to quarter-type, half-type, three-quarter-type, and partial-type.In one embodiment, the drain section (1900ga) may be quarter-shaped and disposed on either side of the flow restrictor (1900g) to allow a small amount of flow from the configuration of the flow restrictor (1900g) to pass through. The drain section (1900ha) may be half-shaped and disposed on both sides of the flow restrictor (1900h), wherein the shape of the flow restrictor (1900h) may be triangular to allow half of the flow from both sides of the configuration of the flow restrictor (1900h) to pass through. The drain section (1900ia) may also be half-shaped, and the drain section (1900ia) may be disposed between the branches of the flow restrictor (1900i) to allow... Half of the flow can flow through the configuration of the flow restrictor (1900i), the bleeder (1900ja) can be quarter-shaped, and the shape of at least one side of the flow restrictor (1900g) can be, but is not limited to, L-shaped or J-shaped, so that the measured flow from one side of the configuration of the flow restrictor (1900j) can flow through, and the bleeder (1900ka) can be three-quarter-shaped or half-shaped and is disposed on the two top sides of the flow restrictor (1900k), wherein the shape of the flow restrictor (1900k) can be, but is not limited to, trapezoidal, octagonal, hexagonal, pentagonal, etc., so that the flow can flow from both sides above the configuration of the flow restrictor (1900k). However, the partial flow restrictors (1900g, 1900h, 1900i, 1900j and 1900k) protect the grinding mill discs (100, 200, 400, 2000, 2100, 2200) from blockage, heating and ensure continuous operation, where the grinding mill is more likely to be blocked, and the blockage of the grinding mill occurs preferentially in high-concentration grinding operation, but may also occur in low-concentration grinding operation, and requires more material flow and good grinding quality in the expected shorter residence time.

[0118] In an embodiment, Figures 20a to 20cA single-helix (2005) configuration for a grinding mill disc (2000) is shown, wherein a single outlet groove (2001, 2001a) is provided between the ribs (2004) or the grooves (2002 or 2000a), wherein the grinding mill disc (2000) may be divided into an even number of sectors, including but not limited to 2, 4, 6, 8, 10, 12, 16, etc. In an exemplary embodiment, the grinding mill disc (2000) is divided into 12 sectors (2000a to 200l), and the outlet groove (2001) is manufactured across the sectors (2000a-2006L) on the grinding disc (2003) in a manner following the projection path of at least one helix (2005) to provide a helical type grinding effect to the input raw material. The outlet groove (2001) is formed between the grooves (2002) to provide a channel for constructing the flow limiter (2008, 2008a) between the ribs (2004) constructed in the grooves (2002). Furthermore, the outlet groove (2001) is manufactured in such a manner that it forms a first spiral (2005a) from the sector (2000f) to the sector (2000a), the first spiral (2005a) gradually increasing in size from the input end (2006) of the grinding disc (2000) toward the output end (2007), while a second spiral (2005b) follows a similar pattern to the first spiral (2005a) from the next sector (200l) immediately to the sector (2000g). Furthermore, during the manufacturing of the spiral (2005) configuration of the outlet groove (2001), some grooves (2002) in the groove (2002) that do not intersect the spiral (2005) path of the outlet groove (2001) can be machined by forming partial outlet grooves (2001a) to enable the configuration of the flow restrictor (2008) between each of the ribs (2004) to be constructed in the groove (2002), and to achieve single-set processing of the spiral (2005) configuration for the grinding mill disc (2000) and the manufacturing features of the grooves (2001, 2002). In one embodiment, the partial outlet groove (2001a) can be manufactured along the output end (2007), wherein the groove (2002) does not intersect the spiral (2005) path of the outlet groove (2001). In another embodiment, the partial outlet groove (2001a) may be configured to connect to a shorter groove (2002a) that does not intersect the spiral (2005) path of the outlet groove and / or the shorter groove (2002a) is shorter in length than the input end (2006) and does not extend completely from the output end (2007).However, the local outlet groove (2001a) allows the grooves (2001, 2002) to be manufactured in a single-set processing manner, and facilitates the construction of a local flow restrictor (2008a) to prevent uncrushed and / or partially crushed material from flowing out of the grinding disc (2000) as output. In another embodiment, as shown. Figure 20b As shown, the spiral (2005) depicts a pulp refining effect focused on specific angles and variations, wherein the spiral (2005) has an angle range of 160° to 175°, and the spiral (2005) is optimized to smoothly and gradually increase the refining load as the pulp gradually moves outward during processing. In one embodiment, the spiral (2005) starts at 0° from the input end (2006) and gradually increases to 180° to reach the ultimate outlet of the output end (2007) of the disc (2000), so that the inlet feed material can enter at 0° and be guided into the spiral (2005) to transform the inlet feed material into treated pulp with the desired effect, to be discharged from the output end (2007) at 180° as an acceptable output. In one embodiment, it will be apparent to those skilled in the art that if the first spiral (2005a) begins at 0° and ends at 180°, then the second spiral (2005b) can begin at 180° and end at 0° or 360° to cover the entire 360° perimeter of the finishing mill disc (2000) with the spiral (2005). Furthermore, the 360° spiral configuration (2000) ensures that the pulp is processed uniformly without sudden increases in pressure or load that could interrupt the finishing process. The figure also illustrates different spiral angles that can be used to tailor the finishing process for specific pulp characteristics, thereby ensuring that the disc (2000) performs optimally for a wide range of finishing tasks. In another embodiment, with Figure 20cAs shown, the current limiter (2008) is constructed in the outlet groove (2001), and the partial current limiter (2008a) is constructed in the partial outlet groove (2001a). In a preferred embodiment, the current limiter (2008) may be constructed in the outlet groove (2001), or the partial current limiter (2008a) may be constructed in the partial outlet groove (2001a), thereby ensuring that only one of the current limiter (2008) and the current limiter (2008a) is present. Similarly, in another preferred embodiment, the outlet groove (2001) may be formed between the two grooves (2002), or the partial outlet groove (2001a) may be formed between the two grooves (2002) or the shorter groove (2002a), thereby ensuring that only one of the outlet groove (2001) and the partial outlet groove (2001a) appears between the pair of grooves (2002) or the shorter groove (2002a) or the rib (2004), enabling processing by means of the single-setup processing method. The grinding disc (2000) is manufactured using a method that forms the configuration of the spiral (2005) to gradually increase the grinding retention time, thereby gradually increasing the grinding load from the input end (2006) toward the output end (2007) without generating excessive local load or material blockage. This facilitates smooth, uniform processing of the raw material along the spiral path (2005a, 2005b) to provide a grinding output at the output end (2007), wherein each sector (2000a to 2000l) contributes equally to the overall grinding process. In one embodiment, the single spiral pattern (2005) of the trajectory of the flow limiter (2008) can be connected clockwise or counterclockwise according to the rotation direction of the grinding disc (2000) to reduce the grinding load.

[0119] In an embodiment, Figures 21a to 21cA double-helix (2105) configuration for a grinding mill disc (2100) is shown, wherein a single outlet groove (2101, 2101a) is provided between the ribs (2104) constructed together with the grooves (2102 or 2100a), wherein the grinding mill disc (2100) is divided into a plurality of sectors (2100a to 2100l), and a grinding disc (2103) is formed across the sectors (2100a to 2100l). An outlet groove (2101) is formed such that only one of the outlet grooves (2101) will appear in a pair of ribs (2104) constructed together with the groove (2102 or 2100a), and the outlet groove (2101) follows at least one of the spiral (2105a, 2105b, 2105c, 2105d) projection paths to provide a double spiral (2105) type fine grinding effect to the input raw material. The outlet groove (2101) is formed between the ribs (2104) constructed together with the groove (2102 or 2100a) to provide a channel, thereby constructing a flow restrictor (2108, 2108a) between the ribs (2104) constructed in the groove (2102). Furthermore, the outlet groove (2101) is manufactured in such a way that the first spiral (2105a) begins from the sector (2100f) and continues to the sector (2100a), the first spiral gradually increasing in size from the input end (2106) of the grinding disc (2100) toward the output end (2107), while the second spiral (2105b) follows a similar pattern to the first spiral (2105a) from the next sector (2100l) immediately to the sector (2100g). The third spiral (2105c) and the fourth spiral (2105d) start from the middle and / or midpoint of the first spiral (2105a) and the second spiral (2105b), respectively, to include a greater number of grooves (2102) within the spiral (2105) pattern formed by the outlet grooves (2101), thereby reducing the number or requirement of local outlet grooves (2101a). This facilitates more balanced grinding and smoother material handling without causing local over-clogging or overloading, thereby reducing clogging, power consumption and extending the life of the grinding disc (2100).Furthermore, in one exemplary embodiment, the spiral (2105c) pattern of the outlet groove (2101) begins from the sector (2100c) and extends to the sector (2000j), starting at the middle of the spiral (2105a) and ending at the middle of the spiral (2105b). Similarly, the spiral (2105d) pattern of the outlet groove (2101) begins from the sector (2100i) and extends to the sector (2000d), with one spiral above the other. The double helix (2105) begins at the middle of the helix (2105b) and ends at the middle of the helix (2105a), without intersecting with either of the helixes (2105a, 2105b), thereby uniformly maintaining material retention on the outer periphery of the finishing mill disc (2100) to eliminate the end or start effect of the helix (2105), and the configuration of the double helix (2105) reduces the number of the local outlet grooves (2101a) to eliminate or reduce localized concentrated processing material retention, thereby improving the pulp finishing effect. However, if any localized outlet grooves (2101a) or a few localized outlet grooves (2101a) exist during the manufacture of the double-helix (2105) type configuration of the outlet groove (2101), some grooves in the groove (2102) that do not intersect with the double-helix (2105) path of the outlet groove (2101) can be treated by forming localized outlet grooves (2101a), making it possible to construct the flow limiter (2108) between each of the ribs (2104) constructed in the groove (2102), and to achieve single-setup processing of the double-helix (2105) type configuration for the grinding mill disc (2100) and the manufacturing features of the grooves (2101, 2102). In one embodiment, if any of the required partial outlet grooves (2101a) can be manufactured above a lower spiral (2105) spanning any of the sectors (2100a-210l) of the groove (2102), then the partial outlet groove (2101a) does not intersect the double spiral (2105) path of the outlet groove (2101). In another embodiment, the partial outlet groove (2101a) can be made to connect to a shorter groove (2102a) that does not intersect the spiral (2105) path of the outlet groove and / or the shorter groove is shorter in length than it extends fully from the input end (2106) to the output end (2107). However, the local outlet groove (2101a) allows the groove (2101, 2102) to be manufactured in a single-set processing manner, and facilitates the construction of a local flow limiter (2108a) to prevent uncrushed or partially crushed material from flowing out of the grinding disc (2100) as output.Furthermore, the single-set processing method can be used to achieve this. Figure 21b The alternating or zigzag pattern (2109) shown is used to design the outlet groove (2101) to achieve the double helix (2105) pattern of the outlet groove (2101). The outlet groove (2101) can be formed such that, in a pair of grooves (2102) or a pair of ribs (2104), only one groove (2101) is near the top side of the output end (2107) of the sector (2100a to 210l) or near the bottom side (2106) of the sector (2100a to 210l); if one outlet groove (2101) of the outlet groove (2101) in a pair of grooves (2102) or a pair of ribs (2104) is formed near the output end (2107), then the next outlet groove (2101) will be formed near the input end (2106); if the first outlet groove (2101) and the helix (2105) are... If any one of the 105a, 2105b) intersects, then the next exit groove and the previous exit groove (2101) will intersect any one of the spirals (2105c, 2105d), and vice versa, such that the exit grooves (2101) are connected in an alternating or zigzag pattern (2109) to alternately intersect all four spirals in the spirals (2105a, 2105b, 2105c, 2105d) to form a double spiral (2105) configuration for the grinding disc (2100) using the single-set processing method, thereby continuously pushing the tool used to form one groove (2102) to another groove (2102) between pairs of grooves (2102) using the single exit groove (2101).

[0120] In one embodiment, the spiral (2105a) starts at 0° from the input end (2106) and gradually increases to 180° to reach the ultimate outlet of the output end (2107) of the disc (2100), allowing the inlet feed material to enter at 0° and be guided into the spiral (2105) to convert the inlet feed material into treated pulp with the desired effect, so as to be discharged from the output end (2107) at 180° as an acceptable output, and the spiral (2105c) starts at 90° from the input end (2106) and gradually increases to 270° to reach the ultimate outlet of the output end (2107) of the disc (2100), allowing the inlet feed material to enter at 90° and be guided into the spiral (2105c) to convert the inlet feed material into treated pulp with the desired effect, so as to be discharged from the output end (2107) at 270° as an acceptable output. In other embodiments, it will be apparent to those skilled in the art that if the spiral (2105a) begins at 0° and ends at 180°, and the spiral (2105c) begins at 90° and ends at 270°, then the spiral (2105b) may begin at 180° and end at 0° or 360°, and the spiral (2105d) may begin at 270° and end at 90°, and vice versa, to cover the entire 360° perimeter of the finishing mill disc (2100) by the double spiral (2105). However, the 360° double spiral configuration (2105) ensures that the pulp is processed efficiently without sudden increases in pressure or load that could cause interruptions to the finishing process.

[0121] In another embodiment, such as Figure 21c and Figure 21d As shown, the double helix (2105) can be constructed with the current limiter (2108) and with or without the local current limiter (2108a). Wherein, Figure 21c and Figure 21d As shown, the flow restrictor (2108) is constructed in the outlet groove (2101), and the partial flow restrictor (2108a) is constructed in the partial outlet groove (2101a) to ensure that only one of the flow restrictors (2108) and the flow restrictor (2108a) appears in a pair of grooves (2102) in any one of the spirals (2105a, 2105b, 2105c, 2105d), as... Figure 21dAs shown. In a preferred embodiment, by skipping the partial outlet groove (2102a), the flow restrictor (2108) can be constructed only in the outlet groove (2101), without the partial flow restrictor (2108a), allowing material to exit from the partial flow restrictor (2108a) of the groove (2102a), as from... Figure 21c As shown. Furthermore, the current limiter (2108a) can be constructed within the local outlet groove (2101a) to ensure that only one of the current limiters (2108) and the current limiter (2108a) appears, including the configuration of the local current limiter (2108a) within the local outlet groove (2102a), which is configured to span any one of the double helices (2105a, 2105b, 2105c, 2105d), as... Figure 21d As shown. Furthermore, in another embodiment, the configuration of only one flow limiter (2108 and 2108a) provides a wide range of pulp refining opportunities to process low-consistency and high-consistency pulps at a lower cost of the refining disc (2100) and a higher refining retention time, depending on material output requirements or applications. The refining load is gradually increased from the input end (2106) towards the output end (2107) without excessive localized loads or material blockage, and facilitates smooth, fluid, and uniform processing of the feedstock along the double-helix path (2105a, 2105b, 2105c, 2105d) to provide a refining output at the output end (2107), wherein each sector (2100a to 2100l) contributes equally to the overall refining process. In one embodiment, the double helix pattern (2105) of the trajectory of the current limiter (2108, 2108a) can be connected in a clockwise or counterclockwise direction according to the rotation direction of the grinding disc (2100) to reduce the grinding load.

[0122] In an embodiment, Figures 22a to 22bA curved pattern (2205) configuration for a fine grinding disc (2200) is shown, wherein a single outlet groove (2201) is provided between the ribs (2204) constructed together with the grooves (2202), wherein the fine grinding disc (2200) is divided into a plurality of sectors (2200a), the plurality of sectors (2200a) including the outlet groove (2202) of the curved pattern (2205) constructed across each of the sectors (2100a) on the grinding disc (2203), such that only one outlet groove (2201) will appear within a valley (2210) formed by a pair of ribs (2204) constructed together with the grooves (2202), and follow the projection path of the curved pattern (2205) that begins and ends in the same sector (2200a), so as to provide a curved-guided fine grinding effect for the input material of each sector (2200a). The outlet groove (2201) is formed in the valley (2210) between the ribs (2204) constructed together with the groove (2202) to provide a channel for constructing a flow limiter (2208) between the ribs (2204) constructed in the groove (2204). Furthermore, the outlet groove (2201) is formed with the curved pattern (2205) extending for a specified length (2210) from the input end (2206) of the sector (2202a) to the output end (2207), enabling the processing of a sufficient amount of input material by means of the grinding disc (2200), and the percentage of the input material gradually increases with the growth of the trajectory of the curved pattern (2205) of the outlet groove (2201). In one embodiment, the initial length (2211) of the bend pattern (2205) can be designed to complete the trajectory of the bend pattern (2202) within the sector (2200a) so that uniform and balanced pulp finishing is performed only within the sector (2200a). In a preferred embodiment, the initial length (2211) of the outlet groove (2202) can be in the range of 10% greater than the sector length (22012) from the input end (2206) to 50% smaller than the sector length (2212) from the input end (2206). Furthermore, for all other construction sectors (2200a) that need to be configured to build the finishing mill disc (2200), the same or similar type of bend pattern (2205) of the outlet groove (2201) can be followed.The curved pattern (2205) configuration of the outlet groove (2201) for the grinding mill disc (2200) results in equal loads on all sectors to facilitate balanced processing, and the geometry of the curved pattern (2205) of the same or similar type facilitates the same or similar type of processing effect on the input material passing through each sector (2200a) to provide the same or similar output quality from each sector (2200a), thereby enhancing the efficiency of the grinding process and the grinding pulp. Furthermore, the curved pattern (2205) ending within each sector (2200a) discharges the processed output from each sector (2200a) to increase the output of the grinding mill disc (2200). Additionally, as... Figure 22b As shown, the flow restrictor (2208) can be constructed in the curved pattern (2205) of the outlet groove (2201), and the ribs (2204) are constructed in the groove (2202) to block the valley (2210) formed between the pair of ribs (2204) by means of the flow restrictor (2208). In one embodiment, the flow restrictor (2208) can have a shape similar to the geometry of the curved pattern (2205) of the outlet groove (2202) to form the trajectory of the curved pattern (2205) of the flow restrictor (2208). The curved pattern (2205) of the trajectory of the flow restrictor (2208) can be connected in a clockwise or counterclockwise direction according to the rotation direction of the grinding disc (2200) to reduce the grinding load. In another embodiment, it will be apparent to those skilled in the art that the orientation of the grooves (2202) formed in the sector (2200a) may be the same or different for all sectors (2200a), all sectors (2200a) being configured to span the mill disc (2200) to obtain the complete configuration of the mill disc (2200), and the orientation of the grooves (2202) formed in the sector (2200a) may be selected according to application requirements or the desired type of pulp milling, but the bending pattern (2205) of the flow limiter (2208) may be the same or similar in all sectors configured to span the mill disc (2200).
