Ball Mills - Mineral Processing & Metallurgy
In present-day practice, the ore is reduced to a size many times finer than can be obtained with crushers. Over a period of many years, various fine grinding mills have been developed and used, but the ball mill has become standard due to its simplicity and low operating cost. A ball mill efficiently operated performs a wide variety of services.

Pharmaceutical Technology: PRACTICAL I : BALL MILLING
Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically. The cylinder contains balls that occupy 30-50% of the total volume, ball size being dependent on feed and mill size.
