Recommended media charge : 70 - 75% of mill's useful vol. Calculation of media load : Example : Attritor mill net volume is 50 Ltr charging with Ø 8 mm balls. 70% of mill's vol = 35 Ltr x 1.6 kg/Ltr (bulk density of Steatite media). That is 56 kg of Steatite grinding media is required for 50 Ltr capacity attritor mill.

The cement mill

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
