The hardness of the selected material shall not exceed the range of the hardness of the material specified by the equipment. Otherwise, the wear of the grinding roller may be increased to a certain extent due to the excessive hardness of the material.

If the Raymond mill contains impurities that are difficult to produce, it will cause it to circulate continuously in the grinding chamber, which will accelerate the wear of the grinding roller.

The wear problem of the grinding roller will increase the production cost of the Raymond grinding equipment, so only the anti-wear can solve the production cost problem. The high-hardness high-quality steel is selected to produce the grinding roller and ensure the material particle size in the Raymond grinding machine production process. It is required and the material does not contain impurities, which can prevent the wear of the parts.
