The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput 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.
Stirred milling technology has been firmly established in the last 20 years as superior to ball mills for fine and regrinding operations due to its superior energy efficiency (Jankovic, et al., 2006). Stirred Mills are now commonly used in many sectors of the mining industry, though they have been used in other industries for many years (Stehr
