HPGR technology is a qualified alternative for largescale comminution circuits and is becoming ever more popular in minerals processing. 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.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill. MORE INFO
