advantages of IsaMill™ing

1 Proven Technology
Specifically developed for rugged metalliferous applications. Designed and proven in our own operations and those of our customers. Every installation operating to design.

2 Improved Flotation/Leach Recovery
Inert grinding media allows control of downstream chemistry and produces clean, polished mineral surfaces providing improved downstream performance while avoiding expensive pulp treatments in flotation or leaching processes. A steep particle size distribution is produced, even in open circuit configuration.

3 High Intensity
The highest intensity grinding technology (>300kW/m³), meaning it is also the most compact. Sizes up to 10,000 litres with 3MW.

4 No Screens
The centripetal classification of the Product Separator removes the need for troublesome fine screens to separate the media and product.

5 Large Size Reduction
The possible reduction ratio of IsaMills™ is far greater than other types of grinding mills at fine sizes. Reduction ratios for full scale IsaMills™ range from 2:1 to over 16:1.

6 The Mill Size You Need
Available in three sizes to meet the needs of your concentrate stream. Take advantage of capital and operating cost savings by minimising the number of mills in your flow sheet.

7 Simple, Fast Maintenance
Uses a fully sealed, disposable rubber lining with simple inspection access. A shut down for inspection and replacement of internal wear parts takes less than 8 hours. Availability of 99% and utilisation of 96% are typical of IsaMills™. Additionally unlike alternative technologies the horizontal, 8 disc layout of the IsaMill™ means it starts easily even after being crash stopped at full load – all 8 discs are available to achieve breakaway torque through the settled media load.

8 Horizontal Design
The horizontal layout was selected for its plug-flow type design. This avoids short circuiting and makes the mill far less sensitive to process disturbances.

9 Compact
Easily the smallest size vessel of any similar power grinding mill. The complete mill and drive train is at one level and is one-fifth the height of typical competitors.

10 Accurate Scale-up
Pilot results are directly scaled to commercial size with 100% accuracy. IsaMills™ have a proven 1:1 direct scale-up to reduce project risk.
