High Pressure Grinding Roll for advanced crushing

With HPGR technology, the feed material is exposed to very high pressure for a short amount of time. The compressive nature of the HPGR mechanics causes the rock to typically crack and cleave along the grain boundaries, weakening the rock structure and exposing the ore particles. This high pressure also creates a large number of fines and ...

High Pressure Grinding Rolls (HPGR) - TAKRAF GmbH

HPGR technology as an alternative to crushers and mills HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming increasingly popular.

(HPGR) high pressure grinding rolls/rollers for cement ...

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid []
