Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill. The ...
These tumblers are called "ball mills" because rock is placed in the tumbler with heavy steel balls. When the tumbler barrel turns the balls are lifted up the wall of the barrel until gravity causes them to drop down onto the ore, crushing it into tiny particles.
