HPGR in the Iron Ore Industry - METS Engineering

HPGR vs. SAG Mill Design 1. Original circuit design SAG/AG mills and ball mills (Huckleberry SABC circuit), however very energy intensive and also energy inefficient accounting for ~80% of the overall process plant energy (depending on the overall process) 2. Changes to design lead to HPGR and ball mill circuits, thus lowering

An insight into platinum mining - African Review

Feb 01, 2012  Fourie said the mine’s power supplies can be highly unstable. South Africa’s state power utility Eskom is contracted to supply 11 kV, but this can occasionally drop to 10.8 kV or increase to 11.2 kV. As concentrators become ever more highly automated, the plant’s equipment is sensitive to fluctuations in power voltage and more likely to trip.
