The IsaMill employs a product separator that retains the media while allowing fine product to exit the mill. Any coarse media or ore particles which enter the product separator region are centrifuged towards the shell. The rotor acts like a centrifugal pump, pumping liquid back to the feed end of the mill.

Accurate scale-up
For an SG of 3 (e.g. Copper), it's 15kg. For an SG of 3.5 (Copper, Lead, Zinc) it's 17.5kg. For an SG of 4 (Pyritic Gold) it's 20. And for an SG of 4.5 (Magnetite) you could expect 22.5kg. Initial testing uses an M4 IsaMill™ to accurately determine the relationship between specific power draw and product size – the 'signature plot'.

Manufacture to Mine
In 1991 the introduction of a Netzsch laboratory stirred mill to the Mount Isa site was a turning point in fine-grinding and ultrafine grinding. The ½ litre bench scale mill resembled a milk shake maker and used fine copper smelter slag as grinding media. Testwork on McArthur River ore started in 1991, and by January 1992, a small pilot scale ...

Open circuit configuration
The product separator is one of the key advantages of the IsaMill™ design. The eight consecutive grinding chambers, and high tip speed of the separator means that the mill constantly delivers sharp sizing performance. There are no screens or trommels to fail or block, any particle that leaves the mill must escape the same centrifugal forces.
