Media ball sizes for example range from about 20 mm for fine grinding to 150 mm for coarse grinding. Tumbling mills are typically employed in the mineral industry for primary grinding (i.e. stage immediately after crushing) in which particles between 5 and 250 mm are reduced in size to between 25 and 300 µm.

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.

Ball mills are also being examined for their potential use in forcing bulky molecules to react. It can be challenging to gain access to a very hindered atom in a molecule using traditional chemistry explains Mack. In mechanochemistry those challenges are overcome because of the sheer force of the pressure moving things together.
