The number of impacts in primary ball mills are far more frequent but have less magnitude than those experienced in SAG mills. The increased frequency is due to the Increase in charge volume (35 – 40% versus 5 – 10%), higher mill speeds, and the larger number of balls per unit charge weight. The lower impact forces are due to a combination

Experimental investigations and modelling of the ball motion

Sep 15, · In order to characterise the stress conditions in planetary ball mills, detailed information about the motion patterns of the grinding balls present in this mill type is needed. The grinding ball movement varies depending on the mill operating parameters, including ball type and size and feed type and size, so these have to be considered carefully.
