Roll Crushers - ScienceDirect
To operate the HPGR Polycom grinding mill, the pressure required is applied hydraulically through four cylinders to the roll that is designed to move laterally. The second roll is immovable. The crushing pressure applied is generally of the order of 200 MPa, but for hard ores, higher pressures are required. For example, in Cyprus Sierrita, a pressure of 340 MPa is used.

High pressure grinding rolls (HPGR) -
High pressure grinding rolls (HPGR) are used for particle reduction in mining operations and aggregates production. Known for energy efficient reduction, HPGRs are most often utilized when the processed material is hard rock. However, they can also refine softer materials like industrial minerals. The smaller models of the HPGRs are particularly productive in producing manufactured sand for ...
