Used for quite a time with great results, considering a coefficient of error if 10%, therefore over sizing, useful to overcome material with high wear rate.Optimum choice of the make-up ball sizes for maximum throughput .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.

different particle sizes and the grinding process is actually not affected by the classifier. In the second case the classifier returns coarse material back to the mill feed and only the fine product is obtained at the output of the grinding circuit. In practice various types of interconnections between mills and classifiers are possible.

Ball Mills – fritsch

Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall.
