the formulae are given as below : 1. For batch type ball mill : M = 0.000929 x D 2 x L. Where M = Weight of the grinding media charge in Kgs. D = Mill internal dia in cms after lining.Recommended grinding media : Ball of Ø 6mm / 8 mm / 10 mm & 12.5 mm. 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).The first compartment is lined with lifter plates
