In addition, no measure of ball mill circuit performance is complete without including an ore grindability component. The functional performance equation (Equation 1) includes ore grindability in the mill grinding efficiency metric. Mill grinding efficiency is essentially the mill grinding rate (t/kWh) normalised by a grindability value (g/rev).
