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 oleg neikov, in handbook of non-ferrous metal powders, 2009 tumbling ball mills. tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. grinding elements in ball mills travel at different velocities. therefore, collision force, direction and kinetic energy between two or more elements vary
