Methods to Estimate AG/SAG Mill Grinding Power

2015-10-20  By repeating tests at different volumetric ball loads but the same initial total charge load one could develop a comprehensive SAG model.The big challenge is to reconcile Malcolm Powell’s Grind Curves for a continuously fed mill controlled to maintain a constant total load volume at values above those giving the maximum throughput or power draw. One could, of course handle rocks sizes in a 6ft
