Grinding Media, Grinding Balls
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. These ...

Figure 3 depicts the effects of media size on grinding times. From this plot, it is shown that a target fineness of 80% < 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes, the target grind is achieved in only 150 minutes.
