Cement Grinding Machine Selection: Vertical Roller Mill VS ...

In roller press, the contact area between the two rollers and the material is small; the material is ground by only passing through the roller press once due to the large grinding ratio. In a vertical mill, there generally are two or more grinding rollers. The contact area between the grinding roller and the grinding disc is large, and the energy utilization rate is higher than that of the roller press.
