Description

Technical Field

[0001] This invention relates to the field of white fused alumina particle grinding technology, specifically to a white fused alumina particle grinding equipment. Background Technology

[0002] In existing technologies, when processing white fused alumina ore into small particles, the ore is first crushed into smaller stones, which are then fed into processing equipment for grinding. The small ore particles are mixed with reaction agents to form a slurry, during which the small particles react. Finally, the small ore particles are bonded and dried to produce different products with grinding or other functions. However, existing processing equipment does not effectively manage the heat generated during the grinding of the ore, which can easily cause environmental pollution. Furthermore, during the reaction process, the slurry cools down due to the evaporation of a large amount of water, which can lead to uneven reaction and excessive residual moisture.

[0003] Therefore, those skilled in the art need a crushed material mixing and processing device that can quickly react and process ore crushed materials and provide a good processing temperature according to the properties of the ore to overcome the above problems. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention proposes a white corundum particle grinding device. To solve the technical deficiencies of the equipment's inability to promptly handle the heat generated during grinding of ore blocks and the additional energy consumption required for drying the ore slurry, this invention creatively incorporates a crushing device and a reaction stirring device. This allows for rapid reaction processing of the ore fragments, while the settling module evaporates most of the water in the ore slurry, enabling it to quickly enter the drying process. This improves the processing efficiency of the material mixing equipment. Simultaneously, a heat transfer system is incorporated to compensate for the heat absorbed during the dehydration of the ore slurry by the heat dissipated from the crushed ore fragments, thereby increasing the energy utilization rate of the material mixing equipment and reducing processing costs.

[0005] The technical solution adopted in this invention is as follows: This invention proposes a white fused alumina particle grinding device, comprising a shell, a chassis, a crushing device, a reaction stirring device, a settling module, and a heat transfer system. The chassis is connected to the bottom of the shell, which defines a processing space. The shell has an inlet and an outlet. The crushing device is located within the processing space and communicates with the inlet. The reaction stirring device is located within the processing space and downstream of the crushing device. The settling module is located within the processing space, downstream of the reaction stirring device, and communicates with the outlet. The heat transfer system is located between the crushing device and the settling module. According to this invention, the crushing device and the reaction stirring device can rapidly react and process the ore fragments. The settling module can evaporate most of the water in the ore slurry, allowing it to quickly enter the drying process, thus improving the processing efficiency of the fragment mixing equipment. Simultaneously, the heat transfer system can use the heat dissipated from the crushed ore fragments to compensate for the heat absorbed during the dehydration of the ore slurry, thereby improving the energy utilization rate of the fragment mixing equipment and reducing processing costs.

[0006] According to some embodiments of the present invention, the crushing device includes a crushing conveyor, a crushing module, and a screening component. The crushing conveyor is connected between the feed inlet and the crushing module, and the screening component is located below the crushing module. The crushing module can grind larger ore blocks into smaller ore particles and small ore particles. Ore particles that meet the particle size requirements can pass through the screening component and enter the subsequent reaction mixing device, while ore particles that do not meet the standards remain in the crushing device. This ensures that the ore material used for the reaction is fully ground, demonstrating the reliability of the crushed material mixing and processing equipment.

[0007] Furthermore, the crushing device includes a secondary crushing system, and the screening component includes a screening element and a transfer element. The screening element is inclined and has multiple through screening holes. The transfer element connects the screening element and the secondary crushing system. The secondary crushing system includes a weighing plate, a lifting component, and a secondary crushing component. The transfer element connects the screening element and the weighing plate. The weighing plate is equipped with a weight sensor. The lifting component is vertically and vertically positioned below the weighing plate. The secondary crushing component is positioned above the transfer element and communicates with the crushing module. Substandard ore particles can slide along the inclined screening element to the transfer element and are then transported from the transfer element to the secondary crushing system, thus preventing ore particle accumulation. Through multiple grinding processes, all ore fragments can be converted into small ore particles that meet the particle size requirements, thereby avoiding waste of ore fragments and improving the reliability of the ore mixing and processing equipment.

[0008] Furthermore, the re-crushing system includes a blocking member, the bottom of the transfer member forms a bearing protrusion protruding towards the re-crushing system, the bearing protrusion forms a bearing groove, the bottom end of the blocking member is movably accommodated in the bearing groove, the blocking member is retractable vertically, the middle part of the blocking member forms a reset protrusion protruding towards the re-crushing system, the top of the blocking member forms a blocking protrusion protruding towards the re-crushing system and a positioning protrusion protruding towards and abutting against the transfer member, the blocking protrusion is adapted to abut against the upper surface of the weighing plate, the top surface of the blocking member is inclined, the bottom surface of the re-crushing member opposite to the blocking member forms an inclined mating surface with the blocking member, and the bottom of the re-crushing member forms a positioning groove for accommodating the positioning protrusion. The blocking component is used to prevent ore particles from falling into the gap between the transfer component and the weighing plate when the weighing plate rises and conveys ore particles. The blocking component can temporarily block the ore particles on the transfer component. After the weighing plate is reset, the blocking component is retracted, and the ore particles on the transfer component can be smoothly conveyed to the weighing plate.

[0009] According to some embodiments of the present invention, the reaction stirring device includes a flow channel, a reaction module, a reaction channel, and a stirring module. The reaction module is connected to the crushing device through the flow channel, and the end of the reaction module away from the flow channel is connected to the stirring module through the reaction channel. In the reaction module, small ore particles are mixed with a reactant and a binder is added to obtain an ore slurry. The heat from the crushing device is absorbed by a heat transfer system, which can reduce the loss of sulfides. When calcium carbonate is added to the small ore particles as a reactant, the calcium carbonate can react with sulfides to generate gypsum and carbon dioxide, which not only improves the binding properties of the ore slurry but also solidifies the sulfur in the ore slurry, reducing environmental pollution and improving the environmental friendliness of the crushing and mixing equipment.

[0010] Furthermore, the lower part of the stirring module has a stirring inlet, and the upper part of the stirring module has a stirring outlet, which can transport the ore slurry to a position closer to the grinding device, so that the ore slurry can absorb the heat dissipated by the grinding device during subsequent dewatering, which reflects the rationality of the structural layout of the crushed material mixing and processing equipment.

[0011] Furthermore, the stirring module includes a stirring shell, a power unit, and a spiral assembly. The spiral assembly includes multiple coaxial spiral blades, which abut against the inner wall of the stirring shell and are arranged vertically. The power unit drives the spiral blades to rotate, and the angle between the inclination direction of the spiral blades and the tangent of the rotation direction of the spiral blades is greater than 90°. This not only fully stirs the ore slurry, ensuring a uniform reaction, but also transports the ore slurry against gravity, thereby enabling the ore slurry to be transported to a position closer to the powder processing device, demonstrating the reliability of the crushed material mixing and processing equipment.

[0012] Furthermore, the settling module includes a settling channel, a settling tank, a recovery device, and an outlet channel. The settling tank is connected to the stirring outlet through the settling channel. The recovery device is installed on the settling tank. The outlet channel connects the discharge port and the settling tank. During the settling process, the coal powder in the ore slurry, due to its low density, can float to the upper layer of the ore slurry. The recovery device recovers the coal powder to obtain coal resources that are difficult to separate from the ore, thus improving the practicality of the crushed material mixing and processing equipment.

[0013] According to some optional embodiments of the present invention, the settling module is located above the crushing device in the vertical direction, one end of the heat transfer system surrounds and abuts the upper part of the crushing module, and the other end of the heat transfer system surrounds and abuts the lower part of the settling tank. This can enhance the heat flow within the heat transfer system, and the heat transfer system can uniformly and effectively absorb the heat dissipated by the crushing module and uniformly and effectively transfer the heat to the settling tank.

[0014] Optionally, the heat transfer system is filled with a flowing heat-conducting fluid, which more effectively transfers the heat from the crushing module to the settling tank, further improving the energy utilization rate of the crushed material mixing and processing equipment and reducing processing costs.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The crushing device and the reaction stirring device can quickly react and process the ore crushed material. The static module can evaporate most of the water in the ore slurry, so that it can quickly enter the drying process, which improves the processing efficiency of the crushed material mixing equipment. At the same time, the heat transfer system can use the heat dissipated by the crushed ore crushed material to compensate for the heat absorbed during the dehydration of the ore slurry, thereby improving the energy utilization rate of the crushed material mixing equipment and reducing the processing cost. (2) The crushing module can grind larger ore blocks into smaller ore particles and small ore particles. Ore particles that meet the particle size requirements can pass through the screening component and enter the subsequent reaction stirring device, while ore particles that do not meet the standard remain in the crushing device. This ensures that the ore material used for the reaction is fully ground, which reflects the reliability of the crushed material mixing and processing equipment. (3) Unqualified ore particles can slide along the inclined screening piece to the transfer piece and be transported from the transfer piece to the re-crushing system, thereby avoiding the accumulation of ore particles. Through multiple grinding, all ore crushed materials can be transformed into ore small particles that meet the particle size requirements, thereby avoiding the waste of ore crushed materials and improving the reliability of crushed material mixing and processing equipment. (4) The blocking component is used to prevent the ore particles conveyed from the transfer component from falling into the gap between the transfer component and the weighing plate when the weighing plate rises and conveys the ore particles. The blocking component can temporarily block the ore particles on the transfer component. After the weighing plate is reset, the blocking component is retracted and the ore particles on the transfer component can be smoothly conveyed to the weighing plate. (5) In the reaction module, the small ore particles are mixed with the reactant and a binder is added to obtain the ore slurry. The heat of the crushing device is absorbed by the heat transfer system, which can reduce the loss of sulfides. When calcium carbonate is added to the small ore particles as a reactant, the calcium carbonate can react with the sulfides to generate gypsum and carbon dioxide, which can not only improve the adhesion of the ore slurry, but also solidify the sulfur in the ore slurry, reduce environmental pollution, and improve the environmental protection of the crushing and mixing equipment. (6) The ore slurry can be transported to a location closer to the grinding device, which facilitates the absorption of heat dissipated by the grinding device during subsequent dewatering of the ore slurry, demonstrating the rationality of the structural layout of the crushing and mixing equipment; (7) It can not only fully stir the ore slurry so that the ore slurry reacts evenly, but also transport the ore slurry against the direction of gravity, thereby realizing the transportation of the ore slurry to a position closer to the powder device, which reflects the reliability of the crushed material mixing and processing equipment; (8) During the settling process of the ore slurry, the coal powder in the ore slurry can float to the upper layer of the ore slurry due to its low density. The recovery device can recover the coal powder to obtain the coal resources that are difficult to separate from the ore, thereby improving the practicality of the crushed material mixing and processing equipment. (9) It can enhance the heat flow in the heat transfer system, and the heat transfer system can absorb the heat dissipated by the crushing module evenly and effectively and transfer the heat evenly and effectively to the settling tank. (10) The heat of the crushing module is transferred to the settling tank more effectively, further improving the energy utilization rate of the crushed material mixing equipment and reducing the processing cost.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] refer to Figures 1-3 This invention proposes a white corundum particle grinding device, including a shell 1, a chassis 2, a crushing device 3, a reaction stirring device 4, a settling module 5, and a heat transfer system 6. The chassis 2 is connected to the bottom of the shell 1, and the shell 1 defines a processing space 11. The shell 1 is a frame structure for the crushed material mixing and processing device, used to accommodate and support other components of the crushed material mixing and processing device. The shell 1 has an inlet 12 and an outlet 13. Before entering the crushed material mixing and processing device, the ore can be crushed into smaller pieces. Then, the ore fragments are fed into the crushed material mixing and processing device from the inlet 12. The ore fragments are further ground in the processing space 11 to form small ore particles. Then, the small ore particles are mixed with a reactant and a binder is added to obtain an ore slurry. After partial dehydration, the ore slurry is discharged from the outlet 13 and can be used as a subsequent drying material.

[0023] The crushing device 3 is located within the processing space 11 and connected to the feed inlet 12. The ore fragments are thoroughly ground within the crushing device 3 to form uniform small ore particles. The reaction stirring device 4 is located within the processing space 11 and downstream of the crushing device 3. The small ore particles are converted into ore slurry within the reaction stirring device 4. The ore slurry is also thoroughly stirred within the reaction stirring device 4, ensuring that the various components of the ore are fully mixed with the reactants. This facilitates rapid ore reaction and improves the processing efficiency of the crushed material mixing equipment. The settling module 5 is located within the processing space 11. In the settling module 5, a large amount of water can be removed from the slurry, which can increase the viscosity of the slurry and allow it to quickly enter the subsequent drying process. During the settling process, the coal powder in the slurry, due to its low density, can float to the upper layer of the slurry. By recovering the coal powder, coal resources that are difficult to separate from the ore can be obtained. The settling module 5 is located downstream of the reaction stirring device 4 and is connected to the discharge port 13. The discharge port 13 can be directly connected to the drying device on the processing production line, so that the processed slurry can be directly transferred to the drying device, thereby improving the processing efficiency of the processing production line.

[0024] The heat transfer system 6 is located between the crushing device 3 and the settling module 5. The crushing device 3 generates a large amount of heat during the grinding of ore fragments, causing the decomposition of sulfides in the fragments or the release of sulfur-containing gases. This not only pollutes the environment but also results in a significant portion of the power consumed by the crushing device 3 being converted into heat and released into the environment, leading to energy waste. During the dehydration process in the settling module 5, the temperature of the ore slurry drops due to water evaporation. At low temperatures, the dehydration efficiency of the ore slurry decreases, and uneven reaction is more likely, reducing its quality as a drying material. The heat transfer system 6 transfers the heat generated by the crushing device 3 during grinding to the settling module 5 for heat preservation during ore slurry dehydration. This achieves the goal of using the heat released from crushing the ore fragments to compensate for the heat absorbed during ore slurry dehydration. Consequently, a portion of the power consumed by the crushing device 3 is used for heat preservation of the settling module 5, eliminating the need for additional heat preservation devices on the settling module 5. This improves the energy utilization rate of the material mixing and processing equipment and reduces processing costs.

[0025] According to the white corundum particle grinding equipment of the present invention, the crushing device 3 and the reaction stirring device 4 can quickly react and process the ore fragments, and the settling module 5 can evaporate most of the water in the ore slurry, so that it can quickly enter the drying process, thereby improving the processing efficiency of the crushed material mixing equipment. At the same time, the heat transfer system 6 can use the heat dissipated by the crushed ore fragments to compensate for the heat absorbed during the dehydration of the ore slurry, thereby improving the energy utilization rate of the crushed material mixing equipment and reducing the processing cost.

[0026] refer to Figures 4-9 According to some embodiments of the present invention, the crushing device 3 includes a crushing conveyor 31, a crushing module 32, and a screening component 33. The crushing conveyor 31 is connected between the feed inlet 12 and the crushing module 32. The crushing conveyor 31 is used to transport ore fragments from the feed inlet 12 to the crushing module 32. The crushing module 32 can grind larger ore blocks into smaller ore particles and ore microparticles. The screening component 33 is located below the crushing module 32. The ground ore material reaches the screening component 33 under the action of gravity. Ore microparticles that meet the particle size requirements can pass through the screening component 33 and enter the subsequent reaction stirring device 4, while ore particles that do not meet the standards can remain in the crushing device 3. By setting the crushing device 3, it can be ensured that the ore material used for reaction is fully ground, which reflects the reliability of the crushed material mixing and processing equipment.

[0027] refer to Figures 4-9Furthermore, the crushing device 3 includes a secondary crushing system 34, and the screening component 33 includes a screening element 331 and a transfer element 332. The screening element 331 is inclined and has multiple through screening holes 3311 formed on it. The transfer element 332 is connected between the screening element 331 and the secondary crushing system 34. Small ore particles that meet the particle size requirements can pass through the screening holes 3311, while ore particles that do not meet the standards can slide along the inclined screening element 331 to the transfer element 332 and be transported from the transfer element 332 to the secondary crushing system 34, thereby avoiding the accumulation of ore particles and demonstrating the reliability of the crushing and mixing equipment. The re-crushing system 34 includes a weighing plate 341, a lifting assembly 342, and a re-crushing component 343. A transfer component 332 connects the screening component 331 and the weighing plate 341. A weight sensor is provided on the weighing plate 341. The lifting assembly 342 is vertically and vertically positioned below the weighing plate 341. The re-crushing component 343 is positioned above the transfer component 332 and communicates with the crushing module 32. The transfer component 332 can transport ore particles to the weighing plate 341. The weight sensor senses the weight of the ore particles accumulated on the weighing plate 341. When a threshold is reached, the lifting assembly 342 can lift the weighing plate 341 and transport the ore particles back to the crushing module 32 through the re-crushing component 343. Then, the lifting assembly 342 lowers the weighing plate 341 and collects the ore particles again, thus achieving a cycle. Through multiple grinding processes, all ore fragments can be converted into small ore particles that meet the particle size requirements, thereby avoiding waste of ore fragments and improving the reliability of the ore mixing and processing equipment. The edge of the weighing plate 341 can form an upward-facing flange, which can prevent ore particles from falling off the weighing plate 341 and ensure that the ore particles are stably stored on the weighing plate 341 during the rising process of the weighing plate 341.

[0028] refer to Figures 4-9Furthermore, the re-crushing system 34 includes a blocking member 344. When the weighing plate 341 rises and conveys ore particles, the blocking member 344 prevents ore particles conveyed from the transfer member 332 from falling into the gap between the transfer member 332 and the weighing plate 341. The blocking member 344 can temporarily block the ore particles on the transfer member 332. After the weighing plate 341 is reset, the blocking member 344 is retracted, and the ore particles on the transfer member 332 can be smoothly conveyed to the weighing plate 341. The bottom of the transfer member 332 forms a bearing protrusion 3321 that protrudes towards the re-crushing system 34. A bearing groove is formed on the bearing protrusion 3321. The bottom end of the blocking member 344 is movably accommodated in the bearing groove. The end face of the bearing protrusion 3321 can be formed as an inclined surface, making the movement of the blocking member 344 more flexible. The blocking member 344 can extend and retract vertically. For example, the blocking member 344 is formed as a telescopic member structure. The upper part of the blocking member 344 is accommodated in the lower part of the blocking member 344, and the upper part of the blocking member 344 can extend from the lower part of the blocking member 344. When the blocking member 344 extends, it can temporarily block the ore particles on the transfer member 332.

[0029] The middle part of the blocking member 344 forms a reset protrusion 3441 that protrudes towards the re-crushing system 34. The top of the blocking member 344 forms a blocking protrusion 3442 that protrudes towards the re-crushing system 34 and a positioning protrusion 3443 that protrudes towards and abuts against the transfer member 332. The blocking protrusion 3442 is adapted to abut against the upper surface of the weighing plate 341, so that when the lifting assembly 342 drives the weighing plate 341 to rise, it can drive the blocking member 344 to rise at the same time. When the end face of the bearing protrusion 3321 is formed as an inclined surface, the blocking member 344 will also move away from the weighing plate 341 during the rising process, so that the blocking protrusion 3442 disengages from the weighing plate 341. The top surface of the blocking member 344 is inclined, and the bottom surface of the re-crushing member 343, which is opposite to the blocking member 344, forms an inclined mating surface with the blocking member 344. This facilitates the movement of the blocking member 344 away from the weighing plate 341. The bottom of the re-crushing member 343 has a positioning groove 3431 for accommodating the positioning protrusion 3443. After the blocking member 344 rises and moves away from the weighing plate 341, the positioning protrusion 3443 can be accommodated in the positioning groove 3431. This allows the blocking member 344 to be fixed when the weighing plate 341 is not in contact with the blocking member 344, thereby improving the blocking effect of the blocking member 344 on the ore particles and preventing the blocking member 344 from affecting the conveying of the ore particles on the weighing plate 341 to the crushing module 32. During the descent of the weighing plate 341, the weighing member 344... The contact reset protrusion 3441 of the weighing plate 341 can drive the blocking member 344 to descend and move the blocking member 344 toward the weighing plate 341, thereby resetting the blocking member 344. The ore particles on the transfer member 332 can continue to be transported to the weighing plate 341. On the other hand, the transfer member 332 and the re-crushing member 343 can be tilted. The ore particles are automatically transported by gravity. After the weighing plate 341 rises, the lifting component 342 can make the end of the weighing plate 341 away from the re-crushing member 343 partially tilt up, which is convenient for transporting the ore to the crushing module 32. For example, when there are multiple lifting components 342, only the lifting component 342 that is farthest from the re-crushing member 343 can be controlled to extend, thereby realizing the partial tilting of the end of the weighing plate 341 away from the re-crushing member 343.

[0030] refer to Figure 9In one embodiment of the present invention, a rotating plate, a rotating shaft, and an elastic element are provided in the bearing groove. The rotating shaft is located in the bearing groove on the side near the transfer member 332. The rotating plate is accommodated in the bearing groove and the end of the rotating plate near the transfer member 32 rotates around the rotating shaft. The elastic element is located between the bottom wall of the bearing groove and the rotating plate. When the weighing plate 344 descends and exerts pressure on the reset protrusion 3441, the bottom of the blocking member 344 is adapted to press on the rotating plate and compress the elastic element. At this time, the rotating plate rotates clockwise and extends downward in a direction inclined away from the transfer member 332. When the weighing plate 344 rises and lifts the blocking member 344, the pressure exerted by the blocking member 344 on the rotating plate is small. The elastic element can lift the rotating plate and cause the rotating plate to rotate counterclockwise and extend upward in a direction inclined away from the transfer member 332. The end of the transfer member 332 near the blocking member 344 can form a retractable leak-proof protrusion that abuts against the blocking member 344. When the rotating plate extends downward in a direction inclined away from the transfer member 332, the blocking member 344 can move in a direction away from the transfer member 332. The leak-proof protrusion can extend and close the gap between the transfer member 332 and the blocking member 344, thereby preventing ore particles from leaking into the gap. When the rotating plate extends upward in a direction inclined away from the transfer member 332, the blocking member 344 can move in a direction close to the transfer member 332. The leak-proof protrusion can shorten and close the gap between the transfer member 332 and the blocking member 344, also preventing ore particles from leaking into the gap.

[0031] refer to Figures 1-3 According to some embodiments of the present invention, the reaction stirring device 4 includes a flow channel 41, a reaction module 42, a reaction channel 43, and a stirring module 44. The reaction module 42 is connected to the crushing device 3 through the flow channel 41. The end of the reaction module 42 away from the flow channel 41 is connected to the stirring module 44 through the reaction channel 43. The small ore particles ground by the crushing device 3 can be transported to the reaction module 42 through the flow channel 41. In the reaction module 42, the small gangue particles are mixed with the reactant and a binder is added to obtain an ore slurry. The heat is absorbed by the heat transfer system 6, which can reduce the loss of sulfides. When calcium carbonate is added to the small ore particles as a reactant, the calcium carbonate can react with the sulfides to generate gypsum and carbon dioxide, which can not only improve the adhesion of the ore slurry, but also solidify the sulfur in the ore slurry, reduce environmental pollution, and improve the environmental friendliness of the crushed material mixing and processing equipment. The ore slurry is transported to the stirring module 44 through the reaction channel 43, which can fully stir the ore slurry and improve the reaction degree of the ore slurry.

[0032] refer to Figure 2 and Figure 3Furthermore, the lower part of the mixing module 44 has a mixing inlet 441, and the upper part of the mixing module 44 has a mixing outlet 442. The ore slurry enters from the lower part of the mixing module 44 and exits from the upper part, which can transport the ore slurry to a position closer to the powdering device, so that the ore slurry can absorb the heat dissipated by the crushing device 3 during subsequent dewatering, which reflects the rationality of the structural layout of the crushed material mixing and processing equipment.

[0033] refer to Figure 2 and Figure 3 Furthermore, the mixing module 44 includes a mixing shell, a power unit, and a spiral assembly. The spiral assembly includes multiple coaxial spiral blades, which abut against the inner wall of the mixing shell and are arranged vertically. The power unit drives the spiral blades to rotate, and the angle between the inclination direction of the spiral blades and the tangent of the rotation direction of the spiral blades is greater than 90°, so that the ore slurry between the spiral blades can spiral upward. This not only fully mixes the ore slurry and makes it react evenly, but also transports the ore slurry against gravity, thereby realizing the transportation of the ore slurry to a position closer to the powder device, demonstrating the reliability of the crushed material mixing and processing equipment.

[0034] refer to Figure 2 and Figure 3 Furthermore, the settling module 5 includes a settling channel 51, a settling tank 52, a recovery device, and an outlet channel 53. The settling tank 52 is connected to the mixing outlet 442 through the settling channel 51. The ore slurry after being stirred can be transported to the settling tank 52 through the settling channel 51. In the settling tank 52, a large amount of water can be removed from the ore slurry, which can increase the viscosity of the ore slurry and allow it to quickly enter the subsequent drying process. The recovery device is located on the settling tank 52. During the settling process of the ore slurry, the coal powder in the ore slurry can float to the upper layer of the ore slurry due to its low density. The recovery device recovers the coal powder to obtain the coal resources that are difficult to separate from the ore, which improves the practicality of the crushed material mixing and processing equipment. The outlet channel 53 connects the discharge port 13 and the settling tank 52 to facilitate the discharge of the ore slurry.

[0035] refer to Figure 2 and Figure 3 According to some optional embodiments of the present invention, the settling module 5 is located above the crushing device 3 in the vertical direction. Since heat rises, the above design can enhance the heat flow in the heat transfer system 6. One end of the heat transfer system 6 surrounds and abuts the upper part of the crushing module 32, and the other end of the heat transfer system 6 surrounds and abuts the lower part of the settling tank 52, so that the heat transfer system 6 can uniformly and effectively absorb the heat dissipated by the crushing module 32 and uniformly and effectively transfer the heat to the settling tank 52.

[0036] refer to Figure 2 and Figure 3Optionally, the heat transfer system 6 is filled with a flowing heat-conducting fluid, which can more effectively transfer the heat of the crushing module 32 to the settling tank 52, further improving the energy utilization rate of the crushed material mixing and processing equipment and reducing processing costs. For example, the heat-conducting fluid may be water, paraffin, or other substances.
