Powders of extremely high fineness can be produced with ball mills and agitated media mills. When wet mills are used, fineness values in the submicron range (>1 µm) can be achieved. These mills are equipped with grinding media (balls, grinding beads) for the grinding process.
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.
