Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral

Trommels remain widely and often work with the screening of mill discharge streams. Tumbling mill (AG, SAG, rod, and ball mills) discharge streams usually pass through a trommel screen attached to the mill outlet to prevent grinding media scats from reaching subsequent processing equipment, and the case of AG/SAG mills, to extract pebbles to send to crushing stage.
