Rubber Ball Mill Liner Wear Rate Estimation Grinding. The wear rate on rubber mill liners (in fact most if not all types of liners) is a function of ore type and PSD, media type and size distribution, mill filling level, speed and operational up-time. I am not aware of a universal formulation to calculate expected wear life.
Optimization Of Mill Performance By Using. 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
