How to increase the output of vertical roller mill?
It can also effectively reduce the wear of the mill body. 3. Hydraulic system pressure. When other factors remain unchanged, the grinding pressure is directly proportional to the output. The greater the grinding pressure, the greater the positive pressure acting on the material on the grinding disc, and the better the grinding effect.
