Increasing the load density of grinding balls in the mill.
With such laying out of the balls of the same diameter, the volume is distributed as follows: 52% goes to grinding balls, 48% is a void volume. That means, to achieve maximum grinding fineness, it is necessary to charge balls of different diameters. This will result in a decrease of dead volume between the grinding media.
