Milling, sometimes also known as fine grinding, pulverising or comminution, is the process of reducing materials to a powder of fine or very fine size. It is distinct from crushing or granulation, which involves size reduction to a rock, pebble or grain size. Milling is used to produce a variety of materials which either have end uses themselves or are raw materials or additives used in the manufacture of other products.

Compared with other grinder machines,especially vertical mill, the grinding ball Mill is of quite simple structure. the ball mill is made up of feeding part, discharging part, gyre part, transmission part (reducer, small transmission gear, motor, and electrical controller) and so on. The hollow axis of Ball mill adopts the cast steel, and the lining can be replaced. The big rotary gear is forged from cast rolling gears. The barrel body of the Ball mill is inlaid with wearable plates.
