Design Method of Ball Mill by Discrete Element Method collected. The diameter of the gibbsite powder was measured using a Master Sizer 2000 (Sysmex Corpora-tion). Details of the experimental conditions are given in Table 2. Results and Discussion 1. Effects of Fins on Ball Motion in the Mill To predict ball mill grinding behavior using the dis-
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
