Ball mill is a essential equipment for further grinding the material after it is crushed. It continues to grind minerals by grinding media to reach a certain fineness to achieve a better grinding effect. Most of mines use overflow ball mill. The mineral will gradually flow to the discharge end with the rotation of the cylinder and the movement ...

8.3.2.2 Ball mills. 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.
