Grinding Balls & Rods
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.

A DEM based scale-up model for tumbling ball mills
The discrete element method (DEM) has been widely used to study particle flow in various industrial applications [11,12], and there have been efforts to apply DEM models to the grinding process. Through DEM simulations of tumbling ball mills, Iwasaki et al. [13] proposed a scale-up procedure based on collision energy of grinding balls.

Planetary Ball Mills
In a planetary ball mill, each jar represents a "planet". This planet is located on a circular platform, the so-called sun wheel. When the sun wheel turns, the jar rotates around its own axis, but in the opposite direction. Thus, centrifugal and Coriolis forces are activated, leading to a rapid acceleration of the grinding balls.
