Description

Technical Field

[0001] This invention relates to the field of graphite grinding machine technology, specifically to an energy-saving graphite grinding machine and its usage method. Background Technology

[0002] As a key piece of equipment for graphite material processing, the graphite grinding machine mainly uses an energy-saving motor to drive the grinding disc or grinding body to rotate, and utilizes the combined effects of friction, extrusion and impact of the grinding media to achieve the refinement of graphite particles.

[0003] In terms of grinding mechanism design, traditional equipment uses a rigidly connected fixed shaft structure, resulting in an unadjustable working gap between the grinding media and the grinding area. This rigid design cannot adapt to the characteristics of graphite raw materials with different hardness and particle size, frequently leading to over-grinding or under-grinding defects during ultrafine grinding. Specifically, when processing low-hardness raw materials, an excessively large fixed gap results in insufficient grinding intensity, causing under-grinding; while when processing high-hardness raw materials, an excessively small gap leads to grinding force overload, which not only damages the graphite crystal structure but also causes significant energy waste due to increased frictional resistance. This rigid structural design severely restricts the equipment's adaptability to different materials.

[0004] In terms of kinematic characteristics, traditional grinding mills use energy-saving motors for single-rotation grinding, with materials crushed solely through sliding friction and compression. This motion mode leads to two prominent problems: first, materials tend to accumulate towards the edge of the grinding disc under centrifugal force, forming a significant grinding blind zone, making it difficult to effectively grind materials at the edges; second, the lack of multi-directional impact and shearing action results in low crushing efficiency. To compensate for these deficiencies, operators are often forced to extend the grinding time driven by the energy-saving motor or increase the rotation speed, which not only increases energy consumption but also exacerbates equipment wear. This inefficient motion mode not only restricts production efficiency but also wastes energy.

[0005] Therefore, an energy-saving graphite grinding machine and its usage method are proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-saving graphite grinding machine and its usage method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving graphite grinding machine, comprising multiple shaft adjustment components, which are used to adjust the mating clearance of the grinding area of ​​the graphite grinding machine. An energy-saving motor is installed at the bottom of the graphite grinding machine, and a grinding disc is provided inside the graphite grinding machine. The output shaft of the energy-saving motor is connected to the main rotating shaft through a reducer. Multiple grinding discs are fixedly connected to the main rotating shaft in a linear array. The shaft adjustment components include a rotating tube, which is rotatably connected to the multiple grinding discs. A through groove is opened inside the rotating tube, and an adjusting block is slidably connected inside the through groove. Multiple adjusting slots are opened in a linear array on the adjusting block, and a cap is threaded to the top of the rotating tube.

[0008] Furthermore, a slot is provided at the top of the rotating tube, and an insert plate is inserted into the slot. Multiple shaft adjusting blocks are arranged in a linear array inside the through groove. A connecting block is fixedly connected between two adjacent shaft adjusting blocks. The connecting block is slidably connected to the groove wall. The top of the top shaft adjusting block is fixedly connected to the lower surface of the adjusting block. Multiple spindles are slidably connected in a linear array on the rotating tube. A grinding body is fixedly connected to both ends of each spindle.

[0009] Furthermore, the graphite grinding machine is also equipped with a reverse grinding component, which includes a hollow gear. The hollow gear is fixedly connected to one end of the rotating tube that extends out of the grinding disc. Multiple support rods are fixedly connected inside the cavity of the graphite grinding machine. The ends of the multiple support rods near the main rotating shaft are fixedly connected to an annular toothed ring. A protective groove ring is rotatably connected to the annular toothed ring.

[0010] Furthermore, the inner wall of the graphite grinding machine has multiple grinding grooves arranged in a straight line.

[0011] Furthermore, the number of gaps between the adjusting groove and the adjusting shaft block and the multiple grinding discs is the same, the slot connects to the through groove, the insert plate is plugged into and adapted to the multiple adjusting grooves, and the connecting block is slidably connected to the groove wall of the through groove.

[0012] Furthermore, the adjusting block is configured as a shape composed of multiple inclined surfaces and multiple straight surfaces. The number of inclined surfaces and straight surfaces of the adjusting block is equal to the number of adjusting grooves, and the distance between two adjacent straight surfaces on the adjusting block is equal to the distance between two adjacent adjusting grooves. The number of adjusting blocks is equal to the number of spindles. The adjusting blocks are slidably connected to the corresponding spindles. The spindles correspond to the positions of the grinding grooves opened in the graphite grinding machine. The adjusting blocks are arranged in a stepped shape, and the top of the adjusting blocks is inclined towards the main rotating shaft.

[0013] Furthermore, the annular gear ring is coaxially arranged with the main rotating shaft, the hollow gear meshes with the inner ring surface of the annular gear ring, the top and bottom sides of the protective groove ring are rotatably connected to the upper and lower surfaces of the annular gear ring respectively, the protective groove ring is rotatably connected to the rotating tube, and the hollow gear is located in the cavity of the protective groove ring.

[0014] A method for using an energy-saving graphite grinding machine includes the following steps:

[0015] Step 1: Initial state check and preparation: Confirm that the screw cap is tightened, the insert plate is inserted into the adjustment groove that coincides with the slot, and the straight face of the adjusting block is fixed to the position of the spindle to ensure that the initial gap of the grinding body is stable.

[0016] Step 2: Dynamic adjustment of grinding gap: Loosen the cap, pull out the insert plate, move the adjusting block up or down, align the target adjusting groove with the slot according to the hardness / particle size of the graphite raw material, insert the insert plate to fix the position of the adjusting block, and tighten the cap to seal the through groove.

[0017] Step 3: Start the grinding operation: Turn on the energy-saving motor, and drive the main shaft to rotate the grinding disc through the reducer. The grinding disc drives the rotating tube to revolve around the main shaft. The pneumatic conveying device guides the graphite material into the grinding tank. The grinding media revolve with the rotating tube and crushes the material through the adjusted gap.

[0018] Step 4: Reverse grinding assembly operation: When the rotating tube revolves, the hollow gear meshes with the ring gear, driving the rotating tube to rotate in the opposite direction, so that the grinding body has a compound motion of "revolving around the main rotating axis" and "rotating in the opposite direction around the center of the rotating tube".

[0019] Step 5: Multi-stage grinding switching: According to the needs of coarse grinding or fine grinding, repeat "Step 2" to adjust the gap (increase the gap for coarse grinding and decrease the gap for fine grinding), without changing the equipment.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] Users can actively adjust the distance between the grinding media and the grinding tank of the graphite grinding machine according to the hardness, particle size and other characteristics of the graphite raw material, so as to realize the dynamic adjustment of the grinding gap. This can accurately match graphite raw materials with different hardness, and solve the problem that the traditional equipment adopts a rigid fixed shaft structure, which causes the gap between the grinding media and the grinding area to remain unchanged and cannot adapt to different materials.

[0022] Meanwhile, the grinding gap can be dynamically adjusted by adjusting the shaft center assembly, allowing the same graphite grinding machine to complete multiple stages of processing such as coarse grinding and fine grinding. This avoids the extra energy consumption caused by the frequent start-stop and switching of multiple fixed-gap machines in traditional processes. The grinding gap can be precisely adjusted according to the needs of different grinding stages. During coarse grinding, the gap is increased to achieve rapid crushing under low load, while during fine grinding, the gap is reduced to achieve precise refinement. This reduces the rework energy consumption caused by over-grinding or under-grinding, keeping the graphite grinding machine in a high-efficiency operating range. It also reduces the additional energy consumption caused by mechanical wear, shortens the overall processing time, and reduces the total running time of the motor in the graphite grinding machine, thus achieving energy saving and consumption reduction in many ways.

[0023] By reversing the operation of the grinding components, the motion of the grinding body is decomposed into the superposition of revolution (following the main shaft) and rotation (reverse rotation), forming a dynamically changing grinding trajectory. At the same time, the centrifugal force field generated by the eccentric motion makes the graphite material more evenly distributed radially in the grinding tank, while the reverse shear force brought by the reverse rotation can prevent the graphite material from accumulating at the edges, allowing the graphite material at the edges that were originally difficult to grind to receive sufficient impact and compression, eliminating the problem of grinding blind spots caused by the single rotational motion of the energy-saving motor in traditional graphite grinding machines.

[0024] Meanwhile, the reverse rotation function of the grinding media further enhances the grinding effect. In the traditional concentric circle motion mode, graphite materials can only be broken by unidirectional sliding friction between the grinding media and the grinding tank. However, the reverse rotation causes the surface of the grinding media and the graphite materials to generate relative motion in multiple directions, forming a composite shear force and impact force. This multidirectional action can not only quickly break the graphite materials, but also effectively destroy the layered structure between graphite particles, accelerate the particle refinement process, and drive all the grinding media to revolve and rotate by using only one energy-saving motor, thereby improving grinding efficiency and achieving the goal of energy saving.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0039] The embodiments provided by this invention:

[0040] Example 1: Please refer to Figures 1 to 7 As shown, an energy-saving graphite grinding machine includes multiple shaft adjustment components. The shaft adjustment components are used to adjust the mating clearance of the grinding area of ​​the graphite grinding machine 11. An energy-saving motor 12 is installed at the bottom of the graphite grinding machine 11. Grinding discs 14 are arranged inside the graphite grinding machine 11. The output shaft of the energy-saving motor 12 is connected to the main rotating shaft 13 through a reducer. Multiple grinding discs 14 are fixedly connected in a linear array on the main rotating shaft 13.

[0041] It should be noted that: (Refer to...) Figure 2 As shown, the multiple grinding discs 14 arranged in a linear array are fitted with a gap. Specifically, two adjacent grinding discs 14 are not in contact with each other and there is a gap. Multiple grinding grooves are arranged in a linear array on the inner side wall of the graphite grinding machine 11, and the gap positions between the grinding grooves and the grinding discs 14 correspond.

[0042] It should be noted that: the graphite grinding mill 11 has a feed inlet (not shown) at the top, and a pneumatic conveying device is provided on the graphite grinding mill 11. The pneumatic conveying device is a known existing technology and is not shown. The pneumatic conveying device provides positive pressure airflow at the top of the chamber of the graphite grinding mill 11 through a high-pressure blower or air compressor, which "push" the graphite material into the grinding tank. The graphite grinding mill 11 has a discharge port (not shown) at the bottom. The graphite grinding mill 11 uses the airflow generated by the pneumatic conveying device to press the ground graphite powder into the discharge port to achieve material discharge.

[0043] An adjusting shaft assembly includes a rotating tube 21, which is rotatably connected to multiple grinding discs 14. A through groove 22 is provided inside the rotating tube 21, and an adjusting block 23 is slidably connected inside the through groove 22. Multiple adjusting slots 24 are arranged in a linear array on the adjusting block 23. A cap 25 is threaded to the top of the rotating tube 21. A slot 26 is provided at the top of the rotating tube 21, and an insert plate 27 is inserted into the slot 26. Multiple adjusting shaft blocks 28 are arranged in a linear array inside the through groove 22. A connecting block 29 is fixedly connected between two adjacent adjusting shaft blocks 28. The connecting block 29 is slidably connected to the groove wall of the through groove 22. The top of the adjusting shaft block 28 is fixedly connected to the lower surface of the adjusting block 23. Multiple spindles 210 are slidably connected in a linear array on the rotating tube 21. A grinding body 211 is fixedly connected to both ends of each spindle 210.

[0044] It should be noted that when the main rotating shaft 13 drives multiple grinding discs 14 to rotate, the multiple grinding discs 14 can drive the rotating tube 21 to rotate synchronously. At this time, the rotating tube 21 revolves around the main rotating shaft 13 with the main rotating shaft 13 as the axis of rotation.

[0045] Among them, the number of gaps between the adjusting groove 24, the adjusting shaft block 28, and the multiple grinding discs 14 is the same.

[0046] Among them, slot 26 is connected to through slot 22, and insert plate 27 is plugged into and adapted to multiple adjustment slots 24.

[0047] Among them, the cap 25 is used to prevent graphite powder from entering the cavity of the through groove 22.

[0048] Among them, the combination of multiple adjustment grooves 24 plays a role similar to a scale or indicator hole. Here, the scale and indicator hole represent the degree of eccentricity of the grinding body 211.

[0049] Specifically: The user can unscrew the cover 25 and then pull out the insert plate 27. The tree hole adjustment block 23 is vertically adjustable inside the through groove 22. At this time, the user can align the corresponding adjustment groove 24 with the slot 26 according to the required scale position, and then insert the insert plate 27 into the rotating tube 21 so that both ends of the insert plate 27 penetrate the rotating tube 21 and the insert plate 27 is inserted into the adjustment groove 24 of the corresponding scale. At this time, the position of the adjustment block 23 after the scale is adjusted is fixed.

[0050] Reference Figure 4As shown, the adjusting block 28 is configured to be a shape composed of multiple inclined surfaces and multiple straight surfaces. The number of inclined surfaces and straight surfaces of the adjusting block 28 is equal to the number of adjusting grooves 24, and the distance between two adjacent straight surfaces on the adjusting block 28 is equal to the distance between two adjacent adjusting grooves 24. Specifically, the multiple adjusting grooves 24 correspond to the multiple straight surfaces and inclined surfaces of the adjusting block 28, and an adjacent straight surface and an inclined surface on the adjusting block 28 form a group. In conjunction with the above, an adjacent straight surface and an inclined surface constitute a scale, which can be adjusted by the user through the above-described operation steps for adjusting the scale position.

[0051] It should be added that: this section does not limit the number of adjusting grooves 24, adjusting shaft blocks 28, and the number of straight and inclined surfaces on adjusting shaft blocks 28. The number of adjusting grooves 24, adjusting shaft blocks 28, and the number of straight and inclined surfaces on adjusting shaft blocks 28 shall be determined according to the actual use.

[0052] Where: Reference Figure 4 As shown, the number of adjusting blocks 28 and spindles 210 are equal, that is, each adjusting block 28 corresponds to one spindle 210. The adjusting blocks 28 and the corresponding spindles 210 are slidably connected, and the spindles 210 correspond to the positions of the grinding grooves opened in the graphite grinding machine 11.

[0053] The inclined surface of the adjusting block 28 serves to guide the spindle 210 to slide on the rotating tube 21, making it easier for the user to adjust the position of the spindle 210 on the rotating tube 21 through the above-mentioned operation steps. The straight surface of the adjusting block 28 serves to restrict the spindle 210 from sliding on the rotating tube 21, making it easier to fix the sliding position of the spindle 210 on the rotating tube 21. Specifically, it is used to fix the eccentric state of the grinding body 211.

[0054] It should be noted that: (Refer to...) Figure 4 As shown, the adjusting block 28 is arranged in a stepped shape, with the top of the adjusting block 28 inclined towards the main rotating shaft 13. Based on the above supplement to the adjusting block 28, the following conclusions can be drawn: When the adjusting block 28 moves downward, the spindle 210 is pushed towards the main rotating shaft 13 by the inclined surface of the adjusting block 28, thereby causing the spindle 210 to move inside the rotating tube 21. At this time, the distance between the grinding body 211 and the grinding groove of the graphite grinding machine 11 increases. Similarly, it can be concluded that when the adjusting block 28 moves upward, the distance between the grinding body 211 and the grinding groove of the graphite grinding machine 11 decreases.

[0055] It should be added that: (refer to) Figure 4 As shown, the position where the mandrel 210 and the adjusting block 28 slide are set in an arc shape. The purpose is to facilitate the sliding of the inclined surface of the adjusting block 28 within the mandrel 210. It should be noted that the two arc surfaces where the mandrel 210 and the adjusting block 28 slide are in contact with the adjusting block 28. The purpose is to ensure the effect of the straight surface of the adjusting block 28 in limiting the mandrel 210.

[0056] In the initial state of the shaft centering assembly, i.e. when no adjustment is required, the internal structures of the shaft centering assembly are as follows:

[0057] The cap 25 is screwed onto the top of the rotating tube 21, sealing the cavity of the through groove 22. Any one of the adjustment grooves 24 coincides with the position of the slot 26, and the insert plate 27 is inserted into the slot 26 and the adjustment groove 24 that coincides with the position of the slot 26. The insert plate 27 fixes and limits the position of the adjustment block 23 inside the through groove 22. Any one of the multiple straight surfaces on the adjusting shaft block 28 is located inside the corresponding spindle 210.

[0058] When the shaft adjustment assembly is running, and the user needs to adjust the distance between the grinding body 211 and the grinding groove of the graphite grinding machine 11, the user loosens the thread and removes the cover 25. At the same time, the user pulls out the insert plate 27. Then the user adjusts the position of the adjustment block 23 inside the through groove 22. At this time, the user can align the corresponding adjustment groove 24 with the slot 26 according to the required scale position.

[0059] While adjusting block 23 is adjusting its position inside the through groove 22, adjusting block 23 drives the top adjusting block 28 to move its position as well. When the top adjusting block 28 moves its position, since all adjusting blocks 28 are connected by connecting block 29, all adjusting blocks 28 move their positions inside the through groove 22. Combined with the above supplement on adjusting block 28, it can be seen that as adjusting block 28 moves, spindle 210 can move inside rotating tube 21. Therefore, it can be concluded that as the user adjusts the corresponding position of adjusting groove 24 and slot 26 according to the required scale position, spindle 210 can be driven to move its position on rotating tube 21. Specifically, the movement of spindle 210 drives the grinding body 211 to move, thereby adjusting the distance between the grinding body 211 and the grinding groove of graphite grinding machine 11.

[0060] When the distance between the grinding bodies 211 on all the adjusting shaft components and the grinding groove of the graphite grinding machine 11 is adjusted to the position required by the user, the user inserts the insert plate 27 into the rotating tube 21 so that both ends of the insert plate 27 pass through the rotating tube 21 and the insert plate 27 is inserted into the corresponding scale adjustment groove 24. At this time, the position of the height adjustment block 23 is fixed, that is, the distance between the grinding bodies 211 and the grinding groove of the graphite grinding machine 11 is fixed. After completion, the user screws the sealing cap 25 to seal the inside of the through groove 22.

[0061] At this point, the shaft centering assembly has finished operating, and the user can start the energy-saving motor 12 and put the graphite material to be ground into the graphite grinder 11. The graphite material enters the grinding tank of the graphite grinder 11 under the action of the pneumatic conveying device. The energy-saving motor 12 drives the main rotating shaft 13 and multiple grinding discs 14 to rotate through the reducer. As the grinding discs 14 rotate, the grinding discs 14 drive the rotating tube 21 to rotate synchronously. The rotating tube 21 revolves around the main rotating shaft 13 with the main rotating shaft 13 as the rotation axis. At this time, multiple grinding bodies 211 that have been adjusted to their positions on the rotating tube 21 are driven to rotate synchronously. While the grinding bodies 211 revolve around the main rotating shaft 13, the graphite material that has entered the grinding tank of the graphite grinder 11 is crushed and ground by the rotating grinding bodies 211.

[0062] In summary, by allowing users to actively adjust the distance between the grinding body 211 and the grinding groove of the graphite grinding machine 11 according to the hardness, particle size and other characteristics of the graphite raw material, the grinding gap can be dynamically adjusted, which can accurately match graphite raw materials of different hardness. This solves the problem that the traditional equipment uses a rigid fixed shaft structure, which results in a fixed gap between the grinding body 211 and the grinding area that cannot adapt to different materials.

[0063] Meanwhile, the grinding gap can be dynamically adjusted by adjusting the shaft center assembly, allowing the same graphite grinding machine 11 to complete multiple stages of processing such as coarse grinding and fine grinding. This avoids the extra energy consumption caused by the frequent start-stop and switching of multiple fixed-gap devices in traditional processes. The grinding gap can be precisely adjusted according to the needs of different grinding stages. During coarse grinding, the gap is increased to achieve rapid crushing under low load, while during fine grinding, the gap is reduced to achieve precise refinement. This reduces the energy consumption of rework caused by over-grinding or under-grinding, keeping the graphite grinding machine 11 in a high-efficiency operating range. It also reduces the additional energy consumption caused by mechanical wear, shortens the overall processing time, and reduces the total running time of the motor in the graphite grinding machine 11, thus achieving energy saving and consumption reduction in many ways.

[0064] Example 2: Refer to Figures 4 to 9 As shown, the graphite grinding machine 11 is also equipped with a reverse grinding assembly, which includes a hollow gear 31. The hollow gear 31 is fixedly connected to one end of the rotating tube 21 that extends out of the grinding disc 14. Multiple support rods 32 are fixedly connected inside the cavity of the graphite grinding machine 11. The ends of the multiple support rods 32 near the main rotating shaft 13 are all fixedly connected to an annular toothed ring 33. A protective groove ring 34 is rotatably connected to the annular toothed ring 33.

[0065] Among them, the annular toothed ring 33 is coaxially arranged with the main rotating shaft 13.

[0066] Where: Reference Figure 9 As shown, the hollow gear 31 meshes with the inner ring surface of the annular gear ring 33.

[0067] Where: Reference Figure 4 , Figure 7as well as Figure 9 The top and bottom sides of the protective groove ring 34 are rotatably connected to the upper and lower surfaces of the annular toothed ring 33, respectively, and the protective groove ring 34 is rotatably connected to the rotating tube 21. The hollow gear 31 is located inside the cavity of the protective groove ring 34. The function of the protective groove ring 34 is to prevent the graphite inside the graphite grinding machine 11 from affecting the meshing relationship between the hollow gear 31 and the annular toothed ring 33 when the graphite grinding machine 11 is running.

[0068] During the operation of the reverse grinding assembly, when the graphite grinding machine 11 is grinding graphite, specifically, the main rotating shaft 13 drives the rotating tube 21 to revolve through the grinding disc 14. At this time, the rotating tube 21 drives the hollow gear 31 to rotate synchronously. During the process of the rotating tube 21 revolving around the main rotating shaft 13, the hollow gear 31, under the meshing action of the ring gear ring 33, causes the hollow gear 31 to drive the rotating tube 21 to rotate on its own axis. The rotation direction of the rotating tube 21 is opposite to the revolution direction of the rotating tube 21. Consequently, the rotating tube 21 drives the multiple grinding bodies 211 on it to move in the same way: during the grinding process, the grinding bodies 211 revolve around the main rotating shaft 13 with the rotating shaft 13 as the rotation center, and the grinding bodies 211 rotate on their own axis in the opposite direction to the revolution direction of the rotating tube 21 with the rotating tube 21 as the rotation center.

[0069] During the revolution of the rotating tube 21 and its reverse rotation, the position of the spindle 210 on the rotating tube 21 can be adjusted by the operation of the shaft adjustment assembly. That is, the operation of the shaft adjustment assembly can make the center of rotation of the grinding body 211 not coincide with the center position of the rotating tube 21 when it rotates around the rotating tube 21. In other words, the shaft adjustment assembly can adjust the grinding body 211 into an eccentric wheel, that is, the grinding body 211 rotates eccentrically.

[0070] After grinding, the graphite powder is pushed into the discharge port by the airflow generated by the pneumatic conveying device of the graphite grinder 11, thus achieving discharge.

[0071] In summary, the operation of the reverse grinding assembly decomposes the motion of the grinding body 211 into revolution, that is, the superposition of the rotation of the main rotating shaft 13 and the rotation of the self, forming a dynamically changing grinding trajectory. At the same time, the centrifugal force field generated by the eccentric motion makes the graphite material more evenly distributed radially in the grinding tank, while the reverse shear force brought by the reverse rotation can prevent the graphite material from accumulating at the edges, so that the graphite material at the edges that are originally difficult to grind can receive sufficient impact and compression, eliminating the problem of grinding blind spots caused by the single rotational motion of the energy-saving motor 12 of the traditional graphite grinding machine 11.

[0072] Meanwhile, the reverse rotation function of the grinding body 211 further enhances the grinding effect. In the traditional concentric circle motion mode, graphite material can only be broken by unidirectional sliding friction between the grinding body 211 and the grinding tank. However, the reverse rotation causes the surface of the grinding body 211 and the graphite material to generate multi-directional relative motion, forming a compound shear force and impact force. This multi-directional action can not only quickly break the graphite material, but also effectively destroy the layered structure between graphite particles, accelerate the particle refinement process, and drive all the grinding bodies 211 to revolve and rotate for grinding by using only one energy-saving motor 12, thereby improving grinding efficiency and achieving the purpose of energy saving.

[0073] Example 3: A method for using an energy-saving graphite grinding machine includes the following steps:

[0074] Step 1: Initial state check and preparation: Confirm that the screw cap 25 is tightened to the rotating tube 21, the insert plate 27 is inserted into the adjustment groove 24 that coincides with the slot 26, and the straight face of the adjusting block 28 is fixed to the position of the spindle 210, to ensure that the initial gap of the grinding body 211 is stable.

[0075] Step 2: Dynamic adjustment of grinding gap: Loosen the cover 25, pull out the insert plate 27, move the adjusting block 23 up or down, align the target adjusting groove 24 with the slot 26 according to the hardness / particle size of the graphite raw material, insert the insert plate 27 to fix the position of the adjusting block 23, and tighten the cover 25 to seal the through groove 22.

[0076] Step 3: Start the grinding operation: Turn on the energy-saving motor 12, and drive the main shaft 13 through the reducer to drive the grinding disc 14 to rotate. The grinding disc 14 drives the rotating tube 21 to revolve around the main shaft 13. The pneumatic conveying device guides the graphite material into the grinding tank. The grinding body 211 revolves with the rotating tube 21 and crushes the material through the adjusted gap.

[0077] Step 4: Reverse grinding assembly operation: When the rotating tube 21 revolves, the hollow gear 31 meshes with the ring gear 33, driving the rotating tube 21 to rotate in the opposite direction, so that the grinding body 211 simultaneously has a compound motion of "revolving around the main rotating shaft 13" and "rotating in the opposite direction around the center of the rotating tube 21".
