In the chemical and power sectors, grinding mill crushes and grinds raw materials, increasing the surface area of materials and creating favorable conditions for shortening the chemical reaction time of materials. With the rapid development of industry and the rapid reduction of resources, the reuse of waste in the production of various departments is very important. The reprocessing of these wastes needs to be broken by grinding mill. Therefore, grinding mill plays an important role in many sectors.

The grinding mill wears too fast. The hardness of the material is too large. In this case, the inner cavity of the grinder should be selected. The equipment is operated at high comminution pressure for a long time, which requires periodic replacement of the lossy parts. The crushed product is not uniform. The crushed product is generally a single peak. If there are double peaks or multiple peaks, the main reason is that the crushing pressure is unstable.
