Description

Technical Field

[0001] The present invention relates to the technical field of pulverizing devices, and in particular to a pulverizing device and a pulverizing method. Background Art

[0002] Pulverizers are widely used in building materials and construction, resource recovery and environmental protection, chemicals, and new materials. In the chemical industry, pulverizers, with their high efficiency, precision, and safety, have become key equipment for raw material pretreatment and product refinement. For example, during the production and processing of nitro compounds, some raw materials must be pulverized to a specific particle size to meet subsequent reaction or purification requirements.

[0003] Patent document CN103447131B discloses a pulverizing device for a pulverizer, comprising a crushing chamber with a feed hopper and a discharge port mounted on it. A cutter wheel is mounted within the crushing chamber via a cutter bearing. A pulley is fixed to one end of the cutter wheel, and a cutter seat is welded to the wheel. A crushing blade is bolted to the cutter seat. An upper cover is mounted on the top of the crushing chamber, with fixing bolts located between the feed hopper and the upper cover. The crushing blades are double-edged and consist of two symmetrically mounted blades on the cutter seat. The cutter seat is fabricated from cold-drawn steel, and the cutter wheel is formed and welded from medium-carbon steel plate. A material storage trough is defined on the cutter wheel. A protective cover is mounted on the outside of the cutter bearing. The pulley is connected to a belt drive unit, which drives the cutter wheel to rotate, causing the crushing blade to rotate with it, achieving crushing. The cutter wheel has a material storage trough, through which the crushed material is discharged through the discharge port under the action of centrifugal force.

[0004] However, this approach also presents the following challenges. When processing certain chemical intermediates, attention must be paid to their chemical properties. For example, nitro compounds pose a potential explosion risk when exposed to heat, friction, or impact. Therefore, crushing methods that could generate sparks, high temperatures, or severe impact should be avoided. The aforementioned prior art uses high-speed rotating blades to crush nitro compounds, which is prone to sparks and frictional heat, posing a safety hazard. Summary of the Invention

[0005] The present invention provides a pulverizing device and a pulverizing method, aiming to solve the problem in the related art that when a high-speed rotating blade pulverizes a nitro compound, sparks or frictional heat are easily generated, which may lead to safety hazards.

[0006] In a first aspect, the present invention provides a pulverizing device, comprising a tank body and a feed port located on the tank body, wherein a crushing assembly, a grinding assembly, a driving assembly, and a guiding assembly are disposed within the tank body; the crushing assembly comprises two sets of crushing bars arranged staggered in a horizontal direction, the driving assembly is connected to the lower ends of the crushing bars to drive the crushing bars to rotate, and the feed port corresponds to the middle of the two sets of crushing bars; the grinding assembly comprises a grinding plate and a grinding roller, the grinding plate being located below the crushing bars, the upper side of the grinding plate being connected to the driving assembly, the lower side of the grinding plate being provided with an arc-shaped portion abutting against the bottom of the grinding roller, the guiding assembly being connected to the grinding roller, and the guiding assembly driving the grinding roller to rotate when the grinding roller moves relative to the tank body; The driving assembly drives the crushing rod and the grinding plate to rotate synchronously, and the grinding roller rotates at the same time. The material crushed by the crushing rod enters between the grinding roller and the arc part, and the grinding roller rotates to cooperate with the arc part to grind the material.

[0007] The effect is that, in the initial state, the drive assembly drives the crushing rod to rotate, so that the upper ends of the two sets of crushing rods are away from each other and in an open state, and the material enters between the two sets of crushing rods through the feed port. Then the drive assembly drives the crushing rod and the grinding plate to rotate synchronously. The crushing rod performs preliminary crushing on the material while rotating, and the preliminary crushed material falls on the grinding plate. The grinding plate drives the grinding roller to move synchronously while rotating. At the same time, the guide assembly drives the grinding roller to rotate. The grinding roller cooperates with the arc portion to grind the preliminary crushed material between the two to form material with a specified particle size. The material is initially crushed by the slow rotation of the crushing rod and then ground by the grinding roller. The slowly rotating crushing rod can reduce the occurrence of sparks. At the same time, the grinding roller grinds the preliminary crushed material, which can shorten the crushing time of the material at the crushing rod and grinding roller, reduce the heat generated during the crushing process, and thus reduce the phenomenon of material overheating, reduce safety hazards, and improve crushing efficiency.

[0008] Preferably, the driving assembly includes a power member, a transmission member, an inner rod, and a sleeve rod. The inner rod is rotatably assembled on the tank body, and the sleeve rod is rotatably sleeved on the outside of the inner rod. The output end of the power member is respectively connected to the sleeve rod and the inner rod through the transmission member to drive the sleeve rod and the inner rod to rotate in opposite directions. The two groups of breaking rods are respectively connected to the inner rod and the sleeve rod. A plurality of makeshift grooves are provided on the sleeve rod, and the breaking rods on the inner rod pass through the makeshift grooves and are connected to the inner rod.

[0009] The effect is that the power member drives the inner rod and the sleeve rod to rotate in opposite directions through the transmission member, and the inner rod and the sleeve rod respectively drive the corresponding crushing rod to rotate, thereby crushing the material.

[0010] Preferably, two groups of grinding plates are provided, the two groups of grinding plates are respectively located below the two groups of crushing rods, and the arc-shaped portion is provided on a side of the grinding plate away from the other grinding plate.

[0011] The effect is that the material after being crushed by the crushing rod enters the grinding plate for subsequent grinding processing.

[0012] Preferably, the two sets of grinding plates are connected to the sleeve rod and the inner rod respectively, and the grinding plates and the crushing rod mounted on the inner rod are symmetrically arranged around the axis of the inner rod.

[0013] The effect is that the grinding plate can rotate synchronously with the crushing rod, and when the two sets of crushing rods rotate to open or close, the corresponding grinding plates are driven to open or close synchronously. During the process, the grinding plate and the crushing rod always correspond to each other, so that the crushed material falls onto the grinding plate.

[0014] Preferably, the guide assembly includes a guide rack and a guide gear. The guide rack is installed on the outside of the tank body, the guide rack is arranged in an arc shape around the inner rod, the guide gear is engaged with the guide rack, and a connecting rod is coaxially fixedly provided at the end of the grinding roller. An arc groove is opened on the tank body, and the connecting rod passes through the arc groove and is coaxially fixedly connected to the guide gear, and the connecting rod is slidably arranged in the arc groove.

[0015] The effect is that when the grinding roller rotates with the grinding plate, the guide gear moves relative to the guide rack, and the rotation of the guide gear drives the grinding roller to rotate, so that the grinding roller cooperates with the arc portion to grind the material.

[0016] Preferably, a support rod is provided on the tank body, and a connecting plate is provided on the end of the connecting rod that is rotatable away from the grinding roller. The support rod is arranged in an arc shape around the inner rod, and the connecting plate is slidably sleeved on the outside of the support rod. An elastic member connected to the support rod is provided on the connecting plate, and the elastic member is used to drive the grinding roller to abut against the arc portion.

[0017] The effect is that the elastic member applies elastic force to the connecting plate, causing the grinding roller to move toward the arc portion, so that the grinding roller always maintains abutment with the arc portion, so that the grinding roller can grind the material between it and the arc portion when it rotates.

[0018] Preferably, the side of the arc-shaped portion facing away from the grinding plate slides and abuts against the inner wall of the tank body, the support rod is located between the two sets of grinding rollers, and a stop sleeve is provided in the middle of the support rod. When the two sets of grinding plates rotate close to each other, the grinding rollers move with the grinding plates, and when the connecting plate abuts against the stop sleeve, the grinding rollers stop moving, and the grinding plates continue to rotate and separate from the grinding rollers.

[0019] The effect is that when the arc portion rotates to the discharge port, the connecting plate abuts against the stop sleeve, the grinding roller stops moving, and the grinding plate continues to rotate, driving the arc portion to separate from the grinding roller, so that the ground material is separated from the arc portion and then discharged through the discharge port.

[0020] Preferably, a discharge port is provided at the bottom of the tank body, and a sieve plate is installed in the discharge port for sliding up and down. The sieve plate is penetrated by a plurality of sieve holes for screening materials.

A push rod is provided at the bottom of the arc portion, and the push rod rotates with the arc portion and passes through a plurality of sieve holes in sequence. When the push rod passes through the sieve hole, the sieve plate is vibrated under the action of the second elastic member to screen the material.

[0021] The effect is that when the arc-shaped part rotates through the screen plate, it drives the push rod to abut against the screen plate, pushing the screen plate downward. After the push rod enters the screen hole, the second elastic member drives the screen plate to move and reset. The screen plate vibrates back and forth repeatedly to perform vibration screening on the material.

[0022] Preferably, the inner top wall of the tank body is configured to be in an arc shape, and the end of the breaker rod facing away from the drive assembly is in sliding contact with the inner wall of the tank body.

[0023] The effect is that the crushing rod can fully contact the material entering the tank body when rotating, thereby reducing the material from entering the grinding plate before preliminary crushing, and improving the crushing effect of the material.

[0024] In a second aspect, the present invention provides a pulverizing method, using the above-mentioned pulverizing device, which comprises the following steps: The power piece drives the inner rod and the sleeve rod to rotate, driving the two sets of breaker bars to rotate in opposite directions, so that the upper ends of the two sets of breaker bars are in an open state; Put the material into the space between the crushing bars through the feed port; The power element drives the two sets of crushing bars to rotate close to each other, and the material between the crushing bars is initially crushed; The crushed material falls onto the grinding plate and then enters between the arc part and the grinding roller; The grinding roller moves with the grinding plate, and the guide gear moves relative to the guide rack, driving the grinding roller to rotate and grind the material in conjunction with the arc part. After the connecting plate moves to match the stop sleeve, the grinding roller stops moving, and the grinding plate continues to move and separates from the grinding roller, and the material between the arc portion and the grinding roller enters the screen plate; The grinding plate continues to rotate, driving the push rod to move through the arc portion. The push rod cooperates with the sieve hole and drives the sieve plate to vibrate under the action of the second elastic member, so that the material is discharged through the discharge port after being vibrated.

[0025] The effect is that after being crushed by the crushing rod, the material is ground by the grinding roller. During the process, the crushing rod rotates slowly, processing the material in sequence until the material is processed to the specified particle size, reducing safety hazards.

[0026] Beneficial effects: The present invention performs primary crushing and grinding of materials by arranging crushing rollers and grinding rollers. During the process, the crushing rod rotates slowly to reduce the occurrence of sparks during crushing, and the material crushing process is divided into two parts, which can not only quickly crush the material into a specified particle size, but also shorten the processing time of the material in the two processes, avoid overheating of the crushing rod or grinding roller surface due to friction in a single process, reduce safety hazards, and improve crushing efficiency.

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] The invention discloses a crushing device.

[0037] Reference Figures 1 to 7 The crushing device includes a tank body 1, which is provided with a feed port 11 and a discharge port 12. The feed port 11 is located above the tank body 1, and the discharge port 12 is located below the tank body 1. A crushing assembly 2, a grinding assembly 3, a drive assembly 4, and a guide assembly 5 are arranged in the tank body 1. The drive assembly 4 cooperates with the crushing assembly 2 and the grinding assembly 3 respectively, and the guide assembly 5 cooperates with the grinding assembly 3. The material to be crushed is added to the tank body 1 through the feed port 11, and the drive assembly 4 cooperates with the crushing assembly 2 to crush the material. The crushed material then enters the grinding assembly 3. Under the action of the drive assembly 4 and the guide assembly 5, the crushing assembly 2 grinds the crushed material to process the material to a specified particle size, and finally the material is discharged through the discharge port 12.

[0038] Reference Figure 1 、 Figure 2 The crushing assembly 2 includes two groups of crushing rods 21, each plurality of crushing rods 21 is arranged as a group, and the plurality of crushing rods 21 in each group are arranged at intervals in the horizontal direction. The two groups of crushing rods 21 are staggered in the horizontal direction. The driving assembly 4 is connected to the crushing rods 21, and the driving assembly 4 drives the two groups of crushing rods 21 to rotate close to each other, and the driving assembly 4 is connected to the bottom of the crushing rods 21. The middle of the two groups of crushing rods 21 corresponds to the feed port 11.

[0039] In the initial state, the drive assembly 4 drives the two sets of crushing bars 21 to rotate away from each other. At this time, the upper ends of the crushing bars 21 are in an open state. After the material enters the tank body 1 through the feed inlet 11, it falls between the two sets of crushing bars 21. The drive assembly 4 then drives the upper ends of the two sets of crushing bars 21 to rotate closer to each other, that is, the upper ends of the crushing bars 21 are gradually retracted. When the two sets of crushing bars 21 approach each other, the material is crushed. Because there is a gap between the crushing bars 21, the crushed material falls downward and separates from the crushing bars 21, and at the same time enters the grinding assembly 3, where it is first preliminarily crushed by the crushing bars 21 to prepare for subsequent grinding.

[0040] Reference Figure 1 The inner top wall of the tank body 1 is set to be an arc shape, and the end of the breaker bar 21 away from the drive assembly 4 is in sliding contact with the inner wall of the tank body 1, that is, the end of the breaker bar 21 is in contact with the arc side of the top of the tank body 1. When the breaker bar 21 rotates, its upper end always keeps in contact with the inner wall of the tank body 1, reducing the phenomenon that the material is separated from the breaker bar 21 before preliminary crushing, so that the breaker bar 21 can fully crush the material when it rotates.

[0041] Reference Figure 1 、 Figure 2 、 Figure 5The grinding assembly 3 includes a grinding plate 31 and a grinding roller 32. The grinding plate 31 is located below the breaking rod 21. The upper side of the grinding plate 31 is connected to the driving assembly 4. An arc-shaped portion 6 is provided below the grinding plate 31. The grinding roller 32 is located in the arc-shaped portion 6, and the arc-shaped portion 6 is located at the bottom of the grinding roller 32 for supporting the grinding roller 32.

[0042] The guide assembly 5 is connected to the grinding roller 32. When the driving assembly 4 drives the grinding plate 31 to rotate, the grinding roller 32 moves accordingly. When the grinding roller 32 moves relative to the tank body 1, the guide assembly 5 drives the grinding roller 32 to rotate.

[0043] The driving assembly 4 drives the crushing rod 21 and the grinding plate 31 to rotate synchronously. After being crushed, the material falls onto the grinding plate 31 and then enters between the arc portion 6 and the grinding roller 32. At the same time, the guiding assembly 5 drives the grinding roller 32 to rotate, and the grinding roller 32 cooperates with the arc portion 6 to grind the material.

[0044] Reference Figure 1 、 Figure 2 、 Figure 7 Two sets of grinding plates 31 are provided, one below each set of crushing bars 21. The arcuate portion 6 is provided on the side of the grinding plate 31 facing away from the other grinding plate 31. When the crushing bars 21 are in the open state, the grinding plates 31 are also in the open state. During rotation, the side of the grinding plates 31 always aligns with the bottom of the crushing bars 21, so that the crushed material falls onto the grinding plates 31. Specifically, the upper end of the crushing bar 21 and the connection between the arcuate portion 6 and the grinding plates 31 are arranged in a vertical direction corresponding to each other, so that the material crushed by the crushing bar 21 enters between the arcuate portion 6 and the grinding roller 32.

[0045] Reference Figure 3 、 Figure 4 The driving assembly 4 includes a power piece 41, a transmission piece 42, an inner rod 43, and a sleeve rod 44. The inner rod 43 is rotatably assembled on the tank body 1, and the inner rod 43 is arranged in the horizontal direction. The sleeve rod 44 is rotatably sleeved on the outside of the inner rod 43. The inner rod 43 is arranged along the arrangement direction of the multiple breaking rods 21. The power piece 41 is arranged as a motor. The power piece 41 is arranged outside the tank body 1. The transmission piece 42 is arranged between the power piece 41 and the inner rod 43. The output end of the power piece 41 is connected to the inner rod 43 and the outer rod respectively through the transmission piece 42. The two groups of breaking rods 21 are connected to the inner rod 43 and the outer rod respectively.

[0046] The power member 41 drives the inner rod 43 and the sleeve rod 44 to rotate in opposite directions through the transmission member 42, that is, drives the two groups of crushing bars 21 to rotate in opposite directions, so that the two groups of crushing bars 21 move away from or approach each other, and the material is crushed when the two groups of crushing bars 21 approach each other.

[0047] Reference Figure 4The transmission member 42 includes an intermediate bevel gear 421, a first bevel gear 422, and a second bevel gear 423. The ends of the inner rod 43 and the sleeve rod 44 extend to the outside of the tank body 1, and the end of the inner rod 43 extends to the outside of the sleeve rod 44. The intermediate bevel gear 421 is coaxially connected to the output end of the power member 41, the first bevel gear 422 is coaxially fixedly connected to the inner rod 43, and the second bevel gear 423 is coaxially fixedly connected to the sleeve rod 44. The intermediate bevel gear 421 is located between the first bevel gear 422 and the second bevel gear 423, and the intermediate bevel gear 421 is meshed with the first bevel gear 422 and the second bevel gear 423 at the same time.

[0048] The power member 41 drives the intermediate bevel gear 421 to rotate. The rotation of the intermediate bevel gear 421 drives the first bevel gear 422 and the second bevel gear 423 to rotate in opposite directions, thereby driving the inner rod 43 and the sleeve rod 44 to rotate in opposite directions.

[0049] Reference Figure 2 、 Figure 4 、 Figure 5 The sleeve rod 44 is provided with a plurality of clearance grooves 441, each corresponding to the multiple breaker rods 21 in each group of breaker rods 21. The breaker rods 21 on the inner rod 43 are connected to the inner rod 43 through the clearance grooves 441. This reduces interference between the sleeve rod 44 and the inner rod 43. An intermediate ring 442 is disposed within the clearance grooves 441 and is fixedly connected to the inner rod 43. The outer side of the intermediate ring 442 is located on the same arc surface as the outer side of the sleeve rod 44.

[0050] Reference Figure 5 The two sets of grinding plates 31 are connected to the sleeve rod 44 and the inner rod 43 respectively. The grinding plates 31 on the sleeve rod 44 are directly connected to the side of the sleeve rod 44, and the grinding plates 31 on the inner rod 43 are connected to the inner rod 43 through the intermediate ring 442. That is, when the power member 41 drives the inner rod 43 and the sleeve rod 44 to rotate, it can drive the two sets of grinding plates 31 to rotate synchronously.

[0051] The grinding plates 31 and breaker bars 21 mounted on the inner rod 43 are symmetrically arranged around the axis of the inner rod 43. When the upper ends of the two sets of breaker bars 21 are retracted, the lower ends of the two sets of grinding plates 31 are also retracted. The breaker bars 21 always align vertically with the grinding plates 31, ensuring that the crushed material falls onto the grinding plates 31. During the grinding process, the breaker bars 21 rotate slowly to reduce heat generated by friction and minimize sparks, thereby improving stability during crushing and grinding.

[0052] Reference Figure 1 、 Figure 3 、 Figure 5The guide assembly 5 includes a guide rack 51 and a guide gear 52. Both the guide rack 51 and the guide gear 52 are arranged outside the tank body 1. The guide rack 51 is arranged in an arc shape around the inner rod 43, that is, the guide rack 51 and the grinding roller 32 move along the same trajectory as the grinding plate 31, and the guide gear 52 is engaged with the guide rack 51. A connecting rod 7 is provided at the end of the grinding roller 32. An arcuate groove 13 is formed through the side of the tank body 1. The connecting rod 7 slides in the arcuate groove 13. The center of the arcuate groove 13 is arranged on the same straight line as the axis of the inner rod 43, that is, the arcuate groove 13 and the guide rack 51 are arranged concentrically. The connecting rod 7 passes through the arcuate groove 13 and is coaxially fixedly connected to the guide gear 52. The guide rack 51 is fixedly provided on the tank body 1.

[0053] When the grinding plate 31 drives the grinding roller 32 to move via the arcuate portion 6, the grinding roller 32 drives the connecting rod 7 to slide within the arcuate groove 13, causing the guide gear 52 to move relative to the guide rack 51. Simultaneously, the guide gear 52 rotates, driving the grinding roller 32 to rotate. Consequently, the grinding roller 32 rotates simultaneously with the rotation of the grinding plate 31, thereby grinding the material.

[0054] Reference Figure 3 、 Figure 4 、 Figure 6 A support rod 8 is provided on the tank body 1. The support rod 8 is arranged outside the tank body 1 and is also arranged in an arc shape around the inner rod 43. A connecting plate 71 is provided on the connecting rod 7. The connecting plate 71 is rotatably connected to the connecting rod 7 and is slidably sleeved on the outside of the support rod 8. That is, the connecting plate 71 can slide on the outside of the support rod 8. A spring 72 is provided on the connecting plate 71. The spring 72 is configured as a spring. One end of the spring is connected to the connecting plate 71 and the other end is connected to the support rod 8. The spring 72 is used to drive the grinding roller 32 to abut against the arc portion 6.

[0055] The spring member 1 72 is located on the side of the connecting plate 71 away from the other connecting plate 71, and the spring member 1 72 is always in a compressed state. The spring member 1 72 pushes the grinding roller 32 toward the arc portion 6 through the connecting plate 71, thereby achieving the grinding roller 32 and the arc portion 6 to maintain abutment state for subsequent grinding.

[0056] In addition, the elastic member 72 with different elasticity can be selected according to different crushing requirements, thereby adjusting the contact force between the grinding roller 32 and the arc portion 6, and then adjusting the force of the grinding roller 32 grinding the material to grind materials of different particle sizes.

[0057] The side of the arc portion 6 facing away from the grinding plate 31 slides against the inner wall of the tank body 1 . Before the arc portion 6 moves to the discharge port 12 , the material is always located above the arc portion 6 so that the grinding roller 32 can fully grind the material.

[0058] Reference Figure 5 、 Figure 6 The support rod 8 is located between the two groups of grinding rollers 32, that is, the support rod 8 cooperates with the connecting plates 71 on the two groups of grinding rollers 32 at the same time. A stop sleeve 81 is provided in the middle of the support rod 8. The diameter of the stop sleeve 81 is larger than the diameter of the support rod 8, so that the connecting plate 71 can abut against the stop sleeve 81 when it moves to the stop sleeve 81, thereby limiting the moving range of the connecting plate 71.

[0059] The two sets of crushing bars 21 approach each other to crush the material, and the two sets of grinding plates 31 also approach each other. At this time, the grinding roller 32 rotates to grind the material. As the grinding roller 32 moves with the grinding plates 31, the connecting plate 71 moves on the support rod 8. After the connecting plate 71 moves to abut against the stopper 81, the connecting plate 71 and the grinding roller 32 stop moving. At this time, the grinding roller 32 is located at the discharge port 12. The grinding plates 31 continue to rotate, and the grinding plates 31 separate from the grinding roller 32, allowing the material between the grinding plates 31 and the grinding roller 32 to fall between the two and be discharged through the discharge port 12.

[0060] Reference Figure 1 、 Figure 7 A sieve plate 9 is provided at the discharge port 12, and a plurality of sieve holes 91 are formed through the sieve plate 9, and the plurality of sieve holes 91 are evenly distributed on the sieve plate 9. The ground material is screened by the sieve plate 9 to break up the agglomerated material and reduce the agglomeration of the discharged material.

[0061] Reference Figure 1 、 Figure 7 The sieve plate 9 is slidably assembled in the discharge port 12. A second elastic member 92 is provided at the bottom of the tank body 1. The second elastic member 92 is also provided at the bottom of the sieve plate 9. The second elastic member 92 is configured as a spring. The second elastic member 92 is connected to the sieve plate 9 and is used to drive the sieve plate 9 to move upward. A push rod 61 is provided at the bottom of the arc portion 6. The push rod 61 passes through a plurality of sieve holes 91 in sequence when rotating with the arc portion 6. When the push rod 61 moves to the sieve plate 9, it pushes the sieve plate 9 to move downward. When the push rod 61 moves into the sieve hole 91, the second elastic member 92 drives the sieve plate 9 to move upward and reset. This process is repeated through a plurality of sieve holes 91 to achieve vibration of the sieve plate 9, so as to screen the material and improve the screening effect of the material.

[0062] Reference Figure 4 、 Figure 7 A plurality of push rods 61 are provided on the arc-shaped portion 6, and the arrangement direction of the plurality of push rods 61 is parallel to the inner rod 43, so that the push rods 61 can pass through all the sieve holes 91 when rotating with the arc-shaped portion 6, and can clean the sieve holes 91 while driving the sieve plate 9 to vibrate, thereby reducing the blockage of the sieve holes 91.

[0063] The implementation principle of the present invention is as follows: the power member 41 drives the inner rod 43 and the sleeve rod 44 to rotate, so that the two groups of crushing rods 21 move away from each other, and the upper ends of the crushing rods 21 are in an open state. Then the material is added to the tank body 1 through the feed port 11, and the material enters between the crushing rods 21. The power member 41 drives the inner rod 43 and the sleeve rod 44 to rotate in opposite directions, and the two groups of crushing rods 21 approach each other to perform preliminary crushing of the material between them. The crushed material is separated from the crushing rod 21 and falls onto the grinding plate 31. The grinding plate 31 rotates synchronously with the crushing rod 21, and the grinding plate 31 drives the grinding roller 32 to rotate. At the same time, the guide gear 52 moves relative to the guide rack 51, so that the grinding roller 32 rotates, and the grinding roller 32 cooperates with the arc portion 6 to grind the material.

[0064] The crushing rod 21 and the grinding roller 32 work simultaneously.
