• Optimum choice of the makeup ball sizes for maximum

Sep 01 2013 A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors including the feed size the product size the mill diameter and the breakage parameters.

• Vibration characteristics of an operating ball mill
