Balls, meaning that the ball size distribution had some effect on crushing and grinding (Zhang et al.However, the horizontal planetary ball mill is different than the tumbling ball mill in many aspects.Djordjevic (2005) studied the influence of ball charge size distribution on the net-power draw of tumbling mill based on DEM modeling.

Closed Circuit Ball Mill In a series of open circuit tests reported by Dorr and Anable (1934) limestone was ground at various feed rates in a 3 ft ball mill.The production of fine material (final product) increased with larger feed rates, and the relationship is a straight line in log-log space.
