Ultrafine Grinding and the IsaMill™ Technology
The IsaMill™ uses inert ceramic grinding media ranging from 1.5 mm to 6.0 mm, that produces clean, polished mineral surfaces resulting in improved leaching kinetics. A steep particle size distribution is produced in the mill. The 98% passing size in the mill is typically less than 2.5 times the 80% passing size, and very little coarse ...

A look at how the IsaMill works
The IsaMill is unlike any other grinding mill1: • It is very high intensity – 300kW/m3, compared with typically 20kW/m3 for ball mills. This means it is easily installed in a small area. • It produces a very sharp size distribution in open circuit. This is due to 8 grinding chambers in series, closed with an internal centrifugal classifier.
