Mill power draw prediction can be carried out using Morrell's power model for tumbling mills. Bond methodThe established technique for determining power requirements for ball mills is the Bond method (Bond, 1961). This method also involves the application of some 'efficiency factors' as described by Rowland (1975).

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 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
