Inside the grinding cylinder body 1 above the end of the guide screen 4 far from the feed hopper 2, a crushing mechanism 5 is provided. Inside the grinding cylinder body 1 below the guide screen 4, a grinding screen 7 is provided. Inside the grinding cylinder body 1 above the grinding screen 7, a grinding mechanism is provided. At the bottom of the grinding cylinder body 1, a discharge port 8 is provided. A discharge valve is arranged on the discharge port 8 to realize the grinding and processing of materials. The guide screening and feeding and the crushing and screening feeding before material grinding enable the materials to enter the grinding evenly, increase the grinding dispersibility and the grinding area, improve the grinding efficiency, realize continuous feeding during grinding, and reduce the dust emission of the grinding equipment at the same time.
[0023] Specifically, the guide screen 4 is composed of a first screen 41 and a second screen 42. The first screen 41 and the second screen 42 are integrally formed. One end of the first screen 41 far from the feed hopper 2 is inclined downward. At the end of the first screen 41 far from the feed hopper 2, the second screen 42 is provided. The second screen 42 is arranged as an arc-shaped screen. The crushing mechanism 5 is arranged inside the grinding cylinder body 1 above the second screen 42. The materials are guided and screened on the first screen 41. The materials passing through the first screen 41 fall above the grinding screen 7. The large-particle materials that are not screened out above the guide screen 4 roll onto the second screen 42.
[0024] Furthermore, the grinding mechanism includes a first grinding roller 6, a second motor 61, a second grinding roller 62, a main gear 63, and a driven gear 64. Inside the grinding cylinder body 1 above the grinding screen 7, the first grinding roller 6 and the second grinding roller 62 are rotatably arranged. One end of the first grinding roller 6 is connected to the output end of the second motor 61 through a coupling. One end of the first grinding roller 6 far from the second motor 61 is connected to the main gear 63 through a rotating shaft passing through the grinding cylinder body 1. One end of the second grinding roller 62 far from the second motor 61 is connected to the driven gear 64 through a rotating shaft passing through the grinding cylinder body 1. The driven gear 64 and the main gear 63 are meshed. The second motor 61 drives the first grinding roller 6 and the main gear 63 to rotate. The rotation of the main gear 63 drives the driven gear 64 meshed with it to rotate. The rotation of the driven gear 64 drives the second grinding roller 62 to rotate. That is, grinding is formed between the first grinding roller 6 and the second grinding roller 62, and grinding is also formed between the first grinding roller 6, the second grinding roller 62 and the grinding screen 7.
[0025] Further, the crushing mechanism 5 includes a crushing rod 51, a crushing knife 52, and a first motor 53. The crushing rod 51 is rotatably provided inside the grinding cylinder 1 above the second screen 42. The crushing knife 52 is provided on the crushing rod 51. One end of the crushing rod 51 is connected to the output end of the first motor 53 through a coupling. The first motor 53 drives the crushing rod 51 to rotate, and the crushing knife 52 on the crushing rod 51 crushes the large-particle materials on the second screen 42.
[0026] Further, a grinding gap is formed between the first grinding roller 6 and the second grinding roller 62. The length directions of the first grinding roller 6 and the second grinding roller 62 are the same as the inclination direction of the first screen 41. The length direction of the crushing rod 51 is vertically and staggeredly arranged with the length direction of the first grinding roller 6, so that the feeding direction of the material is the same as the length direction of the grinding gap, so that the materials passing through the feeding screen 4 and entering the grinding gap between the first grinding roller 6 and the second grinding roller 62 are more dispersed and have a larger contact space.
[0027] Further, the lifting and feeding machine 3 adopts a screw conveyor, and the height of the screw conveyor is correspondingly set with the height of the feeding hopper 2, which is convenient and continuous for lifting and feeding.
[0028] Furthermore, support seats are provided at both opposite ends of the bottom of the grinding cylinder 1. The lower ends of the grinding cylinder 1 and the feeding hopper 2 are both arranged in a V-shaped structure, and the discharging of the grinding cylinder 1 and the feeding hopper 2 is complete.
[0029] The usage method of this embodiment is as follows: The material to be ground is lifted by the feeding machine 3 and conveyed through the feeding port 21 into the feeding hopper 2. The material enters the interior of the grinding cylinder 1 from the discharging port at the bottom of the feeding hopper 2. The material is guided and screened on the first sieve 41. The material passing through the first sieve 41 falls above the grinding sieve 7. The large-particle material that is not screened off above the guiding sieve 4 rolls onto the second sieve 42. The first motor 53 drives the crushing rod 51 to rotate, and the crushing knife 52 on the crushing rod 51 performs crushing treatment on the large-particle material on the second sieve 42. The crushed material is then screened through the second sieve 42 and falls onto the grinding sieve 7. The second motor 61 drives the first grinding roller 6 and the main gear 63 to rotate. The rotation of the main gear 63 drives the driven gear 64 meshing with it to rotate, and the rotation of the driven gear 64 drives the second grinding roller 62 to rotate. That is, grinding is formed between the first grinding roller 6 and the second grinding roller 62, and grinding is also formed between the first grinding roller 6, the second grinding roller 62 and the grinding sieve 7. The ground material falls through the mesh holes of the grinding sieve 7 into the grinding cylinder 1 below the grinding sieve 7. Open the discharge valve on the discharge port 8, and the ground material can be discharged into the collection box to realize the grinding and processing of the material. The setting of the guiding sieve 4 and the crushing mechanism 5 realizes the functions of guiding, screening, feeding, crushing, and screening of the material before grinding, enabling the material to enter the grinding evenly, increasing the grinding dispersion and grinding area, improving the grinding efficiency, realizing continuous feeding during grinding, and reducing the dust generated by the grinding equipment.
