SAG Mill Reline times are a function of the number of pieces to be changed and the time required per piece. Advances in casting and development of progressively larger lining machines have allowed larger and larger individual liner pieces.
All Multotec SAG mill liners are designed by combining computer simulation data and inspection data to optimise charge trajectory and wear life. Find out about our tailored solutions here . Multotec's continuously invests on making its mill liners lighter, more efficient and more costeffective.
SAG Mill Operation at Cortez: Evolution of Liner Design from Current to Future Operations ... in balls overthrowing the toe of the charge and striking the unprotected mill shell liners. This would suggest that a portion of the applied mill power is wasted turning the mill faster to grind the harder ore as well as the subsequent unnecessary and costly liner breakage and mill downtime. • The ...
