Semiautogenous grinding (SAG) mill liner design and development
• to provide the key between the mill charge and the mill shell for charge motion, • to maximize the rate of delivery of thrown grinding media at the toe of the charge to gain the best milling action, • to avoid liner and ball damage and • to provide an economic liner wear life Shell liner design is driven primarily by the practicalOptimising the charge motion to ensure grinding media is hitting the toe of the charge will result in the maximising of ore breakage rates and therefore mill throughput Trajectory analysis also ensures grinding media is not being over thrown onto mill liners where the impact can lead to breakage of balls and liners therefore minimisingGrinding Media Growth Steel
