The use of small diameter media is favored because it results in a large surface area to weight ratio. Also, liner wear decreases as media diameter decreases. However, there is a limit to how small grinding media diameter can become. For one thing, smaller diameter media are more expensive per unit weight.

Schematic drawing of an attrition ball mill. The attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media, usually 12 mm or larger, and run at low rotational speeds of 10–50 rpm.

The range of specific gravity for commercially available grinding media runs from sp.gr. 1.0 for plastics to sp.gr. 15 for tungsten carbide.
