Modifying blasting practices to achieve a more suitable mill feed size – which varies according to the crushing/grinding circuit – can achieve up to a 30% increase in throughput. Following an initial benchmarking of an operation's practices,.

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

Inside the mill, the ore is mixed with water in two rotating SAG mills which use the larger rocks and 8-inch steel balls to reduce the ore to about 10 mm or smaller. We may crush these rocks to a smaller size before feeding them back into the SAG mills, and you can see a small crushing plant between the front and back

Ball mills are grinding machine which employ high carbon steel or special steel balls in ball mills. Ball mill crushes generally finer than those produced in Rod mill, and rod mills are well suited to handle finer feed and to control the smaller size of the product.
