The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
Also we observe for SAG mills that ore competence and feed size distribution, being major influence on rock to steel ratio in the mill, are significant factors that influence SAG mill steel wear. We've observed the abrasion index to be a less useful means of predicting SAG mill grinding media wear. Read More
