High Pressure Grinding Rolls (HPGR) TAKRAF GmbH
HPGR Technology as An Alternative to Crushers and MillsCost and Energy EfficiencyVaried Uses of An HPGRHPGR 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 specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface Feed material can be small[PDF]
