The particle shape of the materials from the roller press and the vertical roller mill is also different. The vertical mill grinds the material by two forces, the extrusion force and the shearing force between the roller and the grinding disc; the roller press grinds the material by only one force, the force between the two grinding rollers.
Vertical Kilns Vertical Shaft Kiln Structures & Working Principles. In cement plants using vertical kilns, the grinded raw materials are first made into wet pellets by adding 12-14% water to the pelletizing pan of the disc pelletizer.Then the wet pellets are fed from the kiln top and discharged from the bottom after calcination.
