Depending on the requirements of the customer, the rice should have a minimum number of broken kernels.

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 highly important.
