The most widely used grinding technologies include SAG, rod, and ball mills. Tower mills were introduced to the metal mining industry in the 1970s and the industry applied them, mostly, to applications with target grinds below 20 μm. Highspeed stirred mills have been used for grinding clays, calcium carbonates and other powders for some time.

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.
