IsaMill - Wikipedia

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. The mixing chamber is filled with the grinding medium (normally sand, smelter slag, or ceramic or steel beads ) and a suspension of water and ore particles, referred to in the minerals industr

IsaMill Technology Used in Effecient Grinding Circuits

The IsaMill™ is a horizontally stirred mill consisting of a series of 8 discs rotating around a shaft driven through a motor and gearbox. The discs operate at tip speeds of 21-23m/s resulting in high energy intensities of up to 300kW/m3. Figure 2 illustrates the layout of the IsaMill™.

IsaMill - NETZSCH Grinding Dispersing

The patented IsaMill is a transformation in grinding technology based on high intensity stirred milling.
