Study of the influence of liner wear on the load behaviour ...

2008-3-28 · As liners wear, it is observed at the plant that the mill throughput or capacity decreases as indicated in Fig. 2. The ball charge is increased at 40, 60 and 80 kh in order to reach the mill design capacity. Usually after 80 kh, the mill can not produce the minimum required capacity and liners are replaced in the mill.
