As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is

Therefore, the average wear rate is lower for 2D meshes than for 1D meshes (with the same initial profile), provided that the liner evolution was predicted with the same wear constant. This reasoning is a strong argument for designing ball mill liner plates with initial grooves similar to those of the worn liner.
