The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding bowl, respectively the mortar. Grinding can be performed dry or wet, and in some cases with liquid nitrogen. In addition to comminution Ball Mills are also useful in the lab for mixing and homogenizing.

The higher break point is reserved for harder wet grinding materials such as enamel as well as dry materials. This angle of break is also determinate upon the size of the mill. Since grinding actions in a larger mill are more severe than that of a smaller mill, the angle of break should be lower for the larger Mills than the smaller.
These interactions enable a range of processes. Depending on the particular product and task at hand, these could include size reduction, dispersion, or deagglomeration processes, as well as emulsification, cell disruption, or homogenization. As the tools of the ball mill, the media have a crucial impact on the outcome of the dispersion or wet grinding process.
