The lengthtodiameter ratio of such a cylinder usually is between 2:1 and 3:1. Ball mills can perform wet or dry grinding. The wet operation usually takes place at relatively lower speeds than dry ones and discharges a slurry with fine materials. These mills also can carry out blending. Ball mills have many key advantages over other mills.

There are many different types of grinding mills (Table 1). Some devices, such as ball mills, are more suitable for coarse materials. These mills use "large" media, ranging in size from 20 mm in diameter and up, to produce material from about ten microns to mesh sizes. Attrition mills are more appropriate for "midrange" size particles.
