Energy and Cost Comparisons of HPGR-based Circuits
2020-4-8 The reported SABC circuit power for the 160 μm grind size was based on actual site data. JKSimMet was used to fit a model to site DCS data. Thus, there was considerable scope to reduce the ball-mill power consumption by using smaller ball-mill grinding media. However, for a final grind of 75 μm, the reported power values for both HPGR-ball ...
