Ball Mills vs Rod Mills

2017-7-3  Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds

Ball Mills - an overview ScienceDirect Topics

Generally, a maximum allowed ball size is situated in the range from D /18 to D /24. The degree of filling the mill with balls also influences the productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30%–35% of its volume.
