The grinding discs agitate the media and ore particles in a slurry that is continuously fed into a feed port. The product separator (dynamic, centripetal classifier) keeps the grinding media inside the mill allowing only the product to exit. Simple control strategies based on power draw enable the IsaMill to produce a constant target product size.

The proprietary IsaMill grating mechanism offers greater intensity triggered milling. It is engineered for finely pulverized prebodies which require a setup shift to present a low-cost treatment. The IsaMill can considerably decrease the energy consumption, media as well as the overall prices of ...
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.
Ultrafine grinding uses a different milling action relative to a conventional ball mill. Fine ceramic media (~3 mm) is agitated through stirring, causing turbulent mixing and attrition. Abrasion is the principal breakage mechanism for size reduction within an IsaMill

High-speed stirred mills are utilized to grind particles below 10mm. Grinding sulphide minerals to as low as 10mm achieve adequate mineral liberation for successful downstream mineral processing operations, such as flotation and leaching. Particle breakage mechanism such as fracture or abrasion, determines the morphological surface features of the product particles.
