Optimum choice of the make-up ball sizes for maximum ...

of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on var-ious factors, including the feed size, the product size, the mill diameter and the breakage parameters. In all cases, binary mixtures of two ball sizes (50.8 mm and 25.4 mm) performed better than a mixture of the three ball sizes.
