The ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axis.

The drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material. The shape of drum liners has a significant impact on mill’s work. Drum Liners of ball mills operated on a large source material have ribs. For mills operated on the fine materials use lining with small ribs or quite smooth. Height, mutual arrangement and shape of the ribs define force of adhesion the grinding ball mill with the drum and the results of the mill’s work. It is important when the character of the lining surface did not change harshly during its deterioration.

Benefits:

1. Savings of up to 35% and increased production.

2. Greater productivity due to shorter grinding time.

3. Greater operating flexibility due to adjustments of the grinding cycles according to the kind of product or raw material.

4. Reduced mechanical wear of the mill (internal walls and balls).
