Improve production while reducing energy consumption. The flexible Hydraulic Roller Press is suitable for both upgrades and new installations.
From this point of view, roller press is superior to vertical mill. 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.
