High Pressure Grinding Roll for advanced crushing |FLSmidth

High Pressure Grinding Roll saving energy and providing results. 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 makes the HPGR an attractive option for heap leach applications.
