Dry and wet grinding methods are equally suitable. As closed cylinders are used for grinding, it is possible to grind toxic substances. Sterile conditions can be maintained with the use of closed cylinders. Compared to other mills, ball mills are inexpensive to install, operate, and maintain. Batch and continuous operation are both possible.

Unlike in the dry mill, where ball impact velocity is the same for all the ball sizes, the impact velocity in a wet mill increases as the ball size increases. It is easy to understand that the liner life is considerably shorter with large balls than with smaller balls, since the impact impulse increases exponentially as ball size increases.
