A two-stage HPGR–horizontal stirred mill circuit has been proposed and its specific energy requirement was determined by a series of stirred mill tests adopting a pilot-scale HPGR and JKSimMet® model, it was shown that this circuit consumed 13 %–31 % less energy than SAB/AGBC/SABC circuits for Cu porphyry ore (Wang, 2013) and …
The nominal mill efficiency, at optimum speed, is 80 Mg/h. The dimensions and the high mass of the rotating elements cause the drive system to be overloaded when the mill filled with copper ore is started. For this reason, the mill is stopped only in the case of a failure or planned maintenance work. The
