1. Introduction. The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of largesize particles, whereas smaller balls are more effective for the breakage of fine particles.
The balls which could be of different diameter occupy 30 50% of the mill volume and 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 he fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
