Ball Mill Sizing | Mill (Grinding) | Industries

Both predict a single size of ball to recharge an operating mill (there are different equations for the range of ball sizes for the first charge of a new mill). The two equations are in Jaime Sepulveda's 'MolyCop tools' software as: d = 6.06 (F80)^0.263 ( Wi)^0.4 (N D)^-0.25. d = 1.354 (F80)^0.5 [ Wi / (Nc D^0.5)]^

[PDF] Effects of mixtures of grinding media of different ...

Abstract The effect of grinding media on milling kinetics has been generally studied using one media shape. However, very little work has been done on investigating mixtures of media shapes. Combining different grinding mechanisms in term of contacts, the volume of grinding zones can be efficiently increased when there is an optimal mixture of two or more grinding media with different shapes ...
