average wear rates in ball mill liners – Grinding Mill China. DEM modelling of liner evolution and its influence on . This information can be used in modelling the wear in ball mill liners with the help of an appropriate wear model. .
The mass rate of wear for these models is developed by multiplying the metal density with the volume rate of wear, resulting in the following equations : adhesive wear m=p^V=p^E 5H, abrasive wear tan(fl) _, m=p^V=p^-^-E (12) (13) It follows that if a rate of energy is dissipated in a given comminution zone of the ball mill (Fig. 1), then ...
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.
