Operating principle of Hydraulic Roller Press . The feed material (cement clinker, slag or other cement raw material) is supplied to the roller press through inlet and here it is directed down between the two rollers which rotate against each other. At the same time, the movable roller is forced towards stationary roller at a fixed hydraulic

Common failure reasons and solutions of roller press

The roller press has been widely used in various grinding operations since it came into being in the mid-1980s. The roller press is composed of two rollers with the same speed and relative rotation. The material is discharged from the feed opening above the roller and enters into the gap between the rollers.
