Ball Mill

Ball mill is a type of grinder used for grinding, blending, and sometimes for mixing materials for use in the process of mineral coatings, paints, ceramics, gold stone and others. It works on the principle of collision and friction: the downsizing of the item being fed into the ball mill is accomplished by impact when the ball falls from the top of the shell. A ball mill consists of a hollow cylindrical shell that rotates around a shaft horizontally or at small angles to the horizontal. It is partially filled with balls. The grinding medium is a ball made of steel (chrome steel), stainless steel, ceramic, or rubber. The inner surface of the cylinder shell is usually coated with an abrasion resistant material such as manganese steel or rubber coating. Less wear occurs in the rubber coated mill, therefore to reduce production costs, the layer that was originally iron can be replaced with a rubber layer, so that the ball mill machine rotating load becomes smaller.
