The grinding media, also referred to as grinding balls or grinding beads, serve as the tools in mills with freely moving grinding media, such as agitator ball mills. The movement of these grinding balls within the mill generates various stresses between the balls and the product, including impact, pressure, friction, and shear.

In test 3, in which the grid was used to segregate the different sizes of balls, a further advantage of about 4 percent in efficiency is shown. The conical mill in test 4 increased the efficiency to 58 percent more than in test 1. The efficiency with the long (6foot) conical mill was about the same as with the short (3foot) one.
