Ball mill grinding efficiency 95.0% = (54 ÷ 64). Benchmark result A ball mill grinding efficiency above 80% is considered "good"; the measured efficiency of 95% is "very good". This suggests that the ball mill is functioning well, and would not see any substantial benefit from further optimization. DISCUSSION
SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill.

For design purposes, you need an estimation or prediction of your SAG Mill's tonnage; well, there are 3 ways to generate good rock "ore" hardness testing data for SAG and ball mill circuit grindability from half drill core. We can abbreviate the discussion by saying there are three "religions" of grinding, and there are small-scale tests suitable for all three of the …
the mill speed as a fraction of the critical speed, ϕC, can be observed by plotting the process power and torque draw superimposed on the relevant motor capability curve. Such plots for an example mill, the SAG mill at Cadia (described by Dunne et al., 2001) is shown in Figure 3.
