Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

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).
