Ball mills are the classic grinding plants: Around the world they are the most common installations. Ball mills convince thanks to their simple principle and low maintenance needs: They are robust, durable and extremely reliable in operation. By using ball mills in closed circuit with a separator, their efficiency can be increased even further.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight

Ball mills are used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out wet or dry, but the former is performed at low speed. Blending of explosives is an example of an application for rubber balls. [2]
ball tube mill design for coal
Ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5 ~ 1.5 , while that of raw coal is 1.5 ~ 4.0 . Therefore, the ball mill should have drying function besides grinding.
