Jan 11, 2016· The balls which could be of different diameter occupy30 – 50 % of the mill volumeand its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition
