2022年3月15日  To develop their model, Morrell et al. (1997) performed HPGR tests along a wide range of roll speed (0.3 to 3 m/s), but large scale HPGRs usually operate within a more limited one. For instance, the control panel of the pilot HPGR used in tests #1 to 4 constrained the roll speed between 11 and 24 rpm (0.46 to 1.01 m/s).

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. The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls.
