Grinding Ball Design - 911 Metallurgist

Ball mass varies and is a function of material density, soundness, and ball size. New ball sizes vary widely compared to nominal theoretical size and weight. The Azzaroni equation size predictions agree well with ball sizes found to be effective for grinding Henderson 203 mm (<8 in.) SAG mill feed and Climax 9.5 mm (0.37 in.) ball mill feeds.

How does a ball mill function? – Swirlzcupcakes

How does a ball mill function? Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material.
