High capacity High Pressure Grinding Rolls for all your use cases. ... Initially introduced as a cement industry product in the mid 1980s, HPGRs soon gained a (minerals processing) foothold in diamond mines. By the late 1990s the HPGR became standard equipment for processing iron ores. Successful hard rock mining installations followed about a ...
Grinding force is provided via hydraulic pumping system and assisted by nitrocharged accumulators. The roller press is designed to operate in choke feed conditions. Feed material is introduced into the gap between the rolls. This action starts to push the moveable roll against the hydraulic rams, compressing the nitrogen in the accumulators.
