### Grinding Media & Lining Media Liner Wear Rate Modelling

The cost of replacement of the metal worn from the working surfaces of the balls and liners of a mill often represents a considerable fraction of the cost of operation of the plant and so is of some real economical importance. In spite of this importance, however, the amount of information in available on this subject is amazingly small and, unfortunately, is insufficient to form the basis of

Dec 01, 2010· Fig. 9 shows the effect of mill charge on the average reduction of liner height (due to wear). The results compare favourably with the experimental data from the Sarcheshmeh SAG mill obtained from data made available by their technical department. The simulation indicates that an increase in the mill charge will increase the wear of liners.

mill liner profiles Valderrama et al. (1996) performed tests of measurement of the wear of lifters in a laboratory ball mill. The object of those tests was to study the role of cascading and cataracting motion of balls on the wear of liners. They used a mill having a diameter of 0.28 m and a length of 0.11 m. The mill
