Energy and Cost Comparisons of HPGR-based Circuits | E & MJ

The HPGR-ball mill circuit when grinding to 75 um compared to 160 um used an extra 4.6 kWh/mt, but for the SABC circuit it only used an extra 1.8 kWh/mt. 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 ...
