For a coal mill, we usually recommend a light classifying liners and for raw mills we recommend heavy classifying liners. If the raw materials are particularly coarse, a mixed solution might be best. This could be either by replacing the first few rings , the first m of the chamber with step lining or combining wave lining
During the operation of the vertical mill, the motor drives the grinding disc to rotate through the main reducer, which drives the rotation of the grinding disc to rotate the three grinding rollers (120° uniform distribution), and the raw coal falls into the center of the grinding disc through the feeding pipe for grinding and grinding. The company coal internal work through three roller mill ...
