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

    Abstract 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. In all cases binary mixtures of two ball sizes (50.8 mm and 25.4 mm
