Due to the loading force applied to the rocker arm 301 by the telescopic piece 302, large-particle materials are crushed by the extrusion generated between the grinding roller 303 and the grinding disc 201; meanwhile, the grinding of small-particle materials can be realized through the sliding friction force generated by the relative movement of the grinding roller 303 and the grinding disc 201.
While the materials are crushed, hot air is introduced into the lower machine body 102 through the air inlet 102d, and the hot air can pass through the air ring 102b and continuously rise; when the material (thrown off the edge of the grinding disc 201 due to centrifugal force) meets the hot gas which passes through the air ring 102b and enters the mill, the material can ascend and enter the powder selecting mechanism 400 through the periphery of the static blades 402 of the separator, and the material and the hot gas perform sufficient heat exchange in the process, so that the moisture is rapidly evaporated. The powder selecting mechanism 400 controls the granularity of finished products at the outlet of the grinding roller 303, particles larger than a specified size are separated and fall back to the grinding disc 201 from the inner cone 404 and the feeding pipe 405 for grinding again, materials meeting the fineness requirement are discharged from the air outlet 104a through the powder selecting mechanism 400 and enter a dust collector connected with the powder outlet, and the collected finished products are sent to a finished product bin.

During the process of inserting the friction blocks 304c one by one, when the friction block 304c is inserted into the corresponding slot 304b-1 of the outer layer 304b through the insert plate 304c-3 thereon, the insert plate 304c-3 can press the pressed slope 304d-2 of the wedge-shaped insert block 304d-1 extending into the slot 304b-1 and push the corresponding arc-shaped slide rod 304d to slide in the arc-shaped channel 304b-3 thereof in a counter-clockwise direction, so that the other wedge-shaped insert block 304d-1 of the arc-shaped slide rod 304d is inserted into the locking slot 304c-31 of the previous insert plate 304c-3 which has been slid into the adjacent slot 304b-1 in the counter-clockwise direction … …, and the insertion of each friction block 304c can lock and limit the previous inserted friction block 304c, therefore, except for the last inserted friction block 304c, the other friction blocks 304c can be fixed in stages, and the last friction block 304c can be fixed by the connecting plate 304f, and finally the assembly of all the friction blocks 304c is completed.
Since the assembly process described above is generally a direct insertion of the respective friction block 304c (the locking process occurs automatically), the assembly is simple and quick, saving time. And because the roller shell assembly 304 is divided into a plurality of modules, the weight is small, and the manual operation is easy.
The friction block 304c of the present invention comprises different structural forms (the outer surfaces of different friction blocks 304c have different structures/materials), and the roller sleeve assembly 304 with different specifications and grinding effects can be assembled by selectively installing different friction blocks 304c on the periphery of the outer sleeve 304b, and the roller sleeve assembly 304 can be directly installed and applied on the hub 303b to realize different grinding processes, so as to obtain different product qualities/yields. Therefore, the structure of the roller sleeve assembly 304 is flexible and changeable, and the applicability is wider; when the grinding mechanism 300 is actually disassembled, assembled and replaced, the whole grinding mechanism is not required to be replaced, safety and reliability are realized, and time is saved.
Preferably, the friction block 304c of the present invention includes at least three types:
1. first friction block 304 c: the wear-resistant steel is formed by forging 42CrMo-A steel at one time, the outer surface of the steel is subjected to surfacing welding in a surfacing mode, the thickness of a wear-resistant layer is 15-20mm, and the hardness is HRC 56-60;

3. third friction block 304 c: the wear-resistant steel is made of high-chromium cast iron grinding materials, and the cracking resistance, the wear resistance and the load bearing capacity are higher than those of the former two materials.
In practice, the friction blocks 304c may be selected to be of a uniform type or mixed (e.g., alternate between first friction block 304c and second friction block 304c), so that a plurality of different application modes can be obtained.
