High Pressure Grinding Rolls (HPGR)
HPGR technology as an alternative to crushers and mills. HPGR technology is a qualified alternative for largescale comminution circuits and is becoming increasingly popular. The technology's working principle is that two counterrotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR ...
