Effect of design and operational parameters on

2017-8-10  Effects of ball mill types, feed sizes and ball surface area on particle morphology have been examined. • Different ball mills lead to various breakage mechanisms and morphologies. • Coarse-grained ground particles are more round and circular. • Circularity and roundness were increased as a result of increasing ball surface area.

Optimum choice of the make-up ball sizes for

2013-9-1  Therefore, it is a common practice in industry to use a mixture of balls rather than balls of a single-size to ensure the efficient grinding of materials of various sizes in the mill. Various formulae have been proposed for the selection of the ball size , . However, as a group, they are not entirely satisfactory because the optimum mixture of balls depends on the feed size as well as the product size.
