Ball Mills - an overview | ScienceDirect Topics

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.

The Three Types of Ball Mills - Minerallurgy

Ball mills are often operated at higher speed than rod mills, so that the larger balls cataract and impact on the ore particles. The work input to a mill increases in proportion to the speed and the ball mills are run at as high a speed as is possible. Applications. Ball mills are used extensively in the mechanical alloying process.
