The cloth net 4 is arranged at the feed inlet 3, the diameter of the mesh of the cloth net 4 is larger as the cloth net is closer to the center of the rotor 5, and the cloth net 4 is used for distributing materials with different particle sizes to be crushed when the materials are input.
After the material to be crushed falls on the material distribution net 4, the larger the diameter of the mesh of the material distribution net 4 is, the closer the material to be crushed with larger particle size is to the center of the shell 1 after passing through the material distribution net 4, and the closer the material to be crushed is to the rotor 5, so that larger centrifugal force effect can be obtained.
The material lining forming device comprises an upper framework plate 6 and a lower framework plate 7, wherein the upper framework plate 6 is connected to a top plate 101 and a side plate 103 of the shell 1, and the lower framework plate 7 is connected to a bottom plate 102 and the side plate 103 of the shell 1 and used for providing a framework for forming a material lining.
In the process of crushing the materials, the materials continuously collide with the upper framework plate 6 and the lower framework plate 7, and after a period of time, the materials form a material lining layer 10 (the material lining layer refers to a material layer formed by high-strength extrusion) on the periphery of the upper framework plate 6 and in a gap area between the upper framework plate 6 and the upper framework plate 6; a material lining 10 is also formed at the outer periphery of the lower skeleton plate 7 and the gap area between the lower skeleton plate 7 and the lower skeleton plate 7. Because the material lining 10 directly strikes, rubs with the material, can show improvement material plastic effect, simultaneously, the formation of material lining 10 can avoid the material directly to strike with casing 1, can effectively avoid casing 1's wearing and tearing, increases life.
The upper framework plates 6 and the upper framework plates 6 can be arranged at intervals and at equal intervals, and can also be arranged up and down in a staggered manner. The same applies to the arrangement of the lower frame plate 7.

In addition, due to the fact that the upper framework plate 6, the anvil block 8 and the lower framework plate 7 are different in structure, hardness and position relation, when the materials to be crushed are in contact with the upper framework plate, the impact force suffered by the materials to be crushed is changed continuously, and the materials are crushed more favorably.
In actual operation, the upper framework plate 6, the anvil block 8 and the lower framework plate 7 are made of high-strength compression-resistant materials, and specifically, wear-resistant layers and the like can be added on the surfaces of the upper framework plate 6, the anvil block 8 and the lower framework plate 7 according to the requirement of crushing materials.
In the process, the materials with large particle size can be impacted with the materials with small particle size for many times to form what is commonly known as a stone-beating effect in the field, so that the materials can be crushed and shaped by multiple impacts, and the crushing effect of the materials is greatly improved.
In the drawing of the embodiment, the upper framework plate 6, the anvil block 8 and the lower framework plate 7 are tightly connected, the upper framework plate 6 and the anvil block 8 are vertically arranged, and the lower framework plate 7 is properly inclined towards the center of the rotor 5, so that the material is not easily blocked in the inner cavity 104 of the housing 1.

Because the small-particle-size materials are closer to the anvil block 8, energy loss is reduced during impact, conversion of energy to crushing energy is increased, meanwhile, the small-particle-size materials bear extrusion or impact of high-energy large-particle-size materials, the crushing ratio of the small-particle-size materials can be improved through the large-beating-size crushing mode, the problem that the small-particle materials are difficult to crush in the prior art is well solved, the materials can be effectively crushed to be less than 5mm from the particle size of more than 10mm, and the crushing efficiency of the high-compressive-strength materials can also be increased.
In the scheme, the upper framework plate 6, the anvil block 8 and the lower framework plate 7 can be flexibly combined to form different forms of mixed crushing cavities, the advantages of two cavity types of stone beating and stone beating can be integrated, the subsequent upper and lower material linings 10 and the intermediate anvil block 8 can enable materials to bear multiple crushing and shaping, the sand forming rate and the sand mold effect in material crushing are improved, abrasion is reduced, and the cost is reduced.
