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.
Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semi-autogenous grinding (SAG) mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding process.
