The gradation of grinding media is also an important factor in improving the efficiency of ball mills. A reasonable gradation can only be calculated after analyzing the performance of the mill, the property of the feed material, and equipment layout in the closed-circuit grinding system.

One research route that has been explored for about half a century is the development of additives to the grinding mill feed that substantially improve the efficiency of grinding. Such additives are termed grinding aids. Grinding aids are used in order to reduce the electrostatic forces between cement particles and their agglomeration.

Several factors affect the efficiency of a ball mill for cement grinding. In this article, we shall be looking at some of these factors that have been proven to influence grinding efficiency: Mill Geometry And Speed. According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed.
