In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight. Since the amount of ore crushed varies as …

Types of Grinding Media Used in Cement Mills. Several types of grinding media are used in cement mills, including: 1. Steel Balls. Steel balls are the most widely used grinding media in cement mills. They are made from carbon steel and are available in various diameters. Steel balls are used to crush and grind the raw material in the …
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 general, small media with tight distributions result in more efficient grinding than wide distributions or mono sized beads. Mono sized beads retard wear and extend the life of …
