In an embodiment of the present application, referring to fig. 1 to 5, a through hole 21a is formed on the tray body 21, the through hole 21a is communicated with two side surfaces of the tray body 21, and the material can pass through the through hole 21 a. The material can flow to the outflow side from the inflow side through the through holes 21a, and the material is prevented from being accumulated around the disc body 21.
In an embodiment of the present application, please refer to fig. 1 to 5, the through holes 21a are disposed on the disc 21 near the circumference of the grinding shaft 10. By the design, the situation that materials and grinding media are accumulated near the grinding shaft 10 to influence the material grinding efficiency is avoided. And as the grinding shaft 10 rotates, the through holes 21a are arranged along the circumferential direction of the grinding shaft 10, so that materials and grinding media around the grinding shaft 10 can rapidly pass through.

In an embodiment of the present application, please refer to fig. 1, the through holes 21a of two adjacent polishing disks 20 are staggered along the axial direction of the polishing shaft 10. Because a plurality of grinding disks 20 do the constant speed rotary motion along with grinding shaft 10, the through-hole 21a of two adjacent grinding disks 20 along the axial staggered arrangement of grinding shaft 10 guarantees that the peripheral material of grinding shaft 10 and grinding medium can all pass through-hole 21 a.
In an embodiment of the present application, referring to fig. 1-5, the polishing disc 20 includes a plurality of protrusions 22 protruding in parallel with the axial direction of the polishing shaft 10, and one end of the protrusion 22 is connected to the disc body 21. When grinding shaft 10 is rotary motion, disk body 21 makes the material be centrifugal motion with grinding medium, protruding 22 makes the mixture of the peripheral material of disk body 21 and grinding medium form the torrent, make material and grinding medium mix more evenly, contact frequency increases between material and the grinding medium, the friction between grinding medium and grinding disk 20 and the material is more violent, protruding 22 can also increase the area of contact of grinding disk 20 and material, make the contact more abundant between material and the grinding medium, better ground material.
In order to further promote more uniform mixing of the material and the grinding medium, increase the contact frequency between the material and the grinding medium, and make the contact between the material and the grinding medium more sufficient, and better grind the material, in an embodiment of the present application, please refer to fig. 1 to 5, the protrusions 22 are uniformly distributed at intervals along the circumferential direction of the disc body 21.
In an embodiment of the present application, please refer to fig. 1-5, the protrusion 22 is disposed on the disc 21 in a circumferential direction away from the grinding shaft 10. The farther the disk body 21 is from the grinding shaft 10, the greater the linear velocity is, and therefore, the protrusion 22 is arranged in the circumferential direction of the disk body 21 away from the grinding shaft 10, so that the materials and the grinding media can be further uniformly mixed, the contact frequency between the materials and the grinding media is increased, the contact between the materials and the grinding media is more sufficient, and the materials are better ground.
In one embodiment of the present application, the protrusions 22 of two adjacent grinding disks 20 are staggered along the axial direction of the grinding shaft 10. This design allows for more uniform mixing of the material and grinding media.
In an embodiment of the present application, referring to fig. 1 to 5, the disc body 21 includes a first disc body 211 and a second disc body 212, a cross-sectional shape of the first disc body 211 is different from a cross-sectional shape of the second disc body 212, and the first disc body 211 and the second disc body 212 are arranged in a staggered manner along an axial direction of the grinding shaft 10. The cross-sectional shape of the tray body 21 may be a polygon such as: triangle, quadrangle, pentagon, hexagon, etc., and may be circular, oval, etc. The cross-sectional shape of the first tray body 211 is different from the cross-sectional shape of the second tray body 212, for example, when the first tray body 211 is a quadrangle, the second tray body 212 is a triangle, and the second tray body 212 may be a non-quadrangular polygon such as a pentagon and a hexagon, or may be a circle and an ellipse; when the first tray 211 is circular, the second tray 212 may be polygonal, such as triangle, quadrangle, pentagon, hexagon, etc., or elliptical, etc., that is, the cross-sectional shape of the first tray 211 is not consistent with the cross-sectional shape of the second tray 212. The first disc body 211 and the second disc body 212 with different cross-sectional shapes are arranged in a staggered mode along the axial direction of the grinding shaft 10, when the grinding shaft 10 rotates, the first disc body 211 and the second disc body 212 enable materials and grinding media to do centrifugal motion, and due to the fact that the cross-sectional shape of the first disc body 211 is different from that of the second disc body 212, the mixture of the materials and the grinding media forms turbulence, the materials and the grinding media are mixed more uniformly, the contact frequency between the materials and the grinding media is increased, the materials and the grinding media are enabled to be in contact with each other more fully, and the materials are ground better.
In one embodiment of the present application, the distance between two adjacent grinding disks 20 gradually increases along the material traveling direction. The smaller the distance between two adjacent grinding disks 20 is, the more grinding media are left between two adjacent grinding disks 20, the more the grinding media between two adjacent grinding disks 20 wear the grinding disks 20, and the faster the grinding speed of the material between two adjacent grinding disks 20 is. The distance between two adjacent grinding disks 20 is gradually increased along the material advancing direction, and the closer the distance between two adjacent grinding disks 20 on the material inflow side is, the smaller the distance is, the more convenient the material is to be quickly ground; because the volume of the material closer to the material outflow side is closer to the target volume, the distance between two adjacent grinding discs 20 closer to the material outflow side is larger, unnecessary abrasion of the grinding medium on the grinding discs 20 can be avoided, unnecessary abrasion of the grinding medium per se can also be avoided, and the cost is saved. Meanwhile, because the thickness of the disc body 21 close to the material inflow side is greater than that of the disc body 21 close to the material outflow side, the disc body 21 close to the material inflow side and the disc body 21 close to the material outflow side have relatively consistent working lives, and when the disc body 21 close to the material inflow side reaches the wear degree to be replaced, the disc body 21 close to the material outflow side also reaches the wear degree to be replaced.
