1 General Albion Process Description - Core Resources

over 100 IsaMill™ installations, ensuring a trouble free commissioning. The IsaMill™ will contain up to eight discs on the shaft, with each disc acting as a separate grinding element. The operating mechanism for the IsaMill™ is shown in Figure 5. This allows the IsaMill™ to be operated in open circuit without the need for cyclones.

IsaMill™ - Glencore

In short, IsaMill™ reduces the energy cost, media cost and capital cost of fine-grinding. The IsaMill™ is used extensively in base metals, PGM, gold processing and magnetite grinding applications. And the power capacity of an IsaMill™ ranges from 75kW to 3.8mW. IsaMill™ is the real-world specification of choice in: mainstream grinding.

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.

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.

Ultrafine Grinding Of Pyrite

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.
