The correct sizes are often determined by trial and error, primary grinding usually requiring a graded charge of 10-5 cm diameter balls, and secondary grinding requiring 5-2 cm. Concha et al. (1988) have developed a method to calculate ball mill charge by using a grinding circuit simulator with a model of ball wear in a tumbling mill.

Ball mills. Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are more suitable for fine grinding. Balls are also lighter, so the kinetic energy of a single dropping ball is smaller than a rod.

As a result, the grinding process is swift and efficient. However, steel burr mills tend to produce a slightly coarser flour compared to stone burr mills. I find steel burr mills to be more versatile, as they can easily handle oily or high-moisture grains that may cause clogging issues in stone burr mills.
