IsaMill™ has evolved to be the most effective stirred mill in the world, with the smallest total footprint and delivering the most consistent particle size distribution.

With more than 130 installations around the world, it’s proven and reliable. 

And now there’s a series of steps to make sure you know exactly which mill will deliver the best fine grinding, including a new online calculator.

How IsaMill™ works

The IsaMill™ is horizontal so its product discharge is not fighting gravity like a vertical mill can.  This means it avoids short circuits and maximises availability.  IsaMill™ is the only horizontal fine grinding mill in the world. 

It’s safe and easy to maintain.  It’s not suspended.  You just slide it open.
The IsaMill™ is also light.  It’s evolved to just one level, with an incredibly small volume of concrete and structural steel. This means it’s about a third the height and weight of some other grinding mills.

More power than other mills 

The IsaMill™ is incredibly efficient and intense. With 8 grinding discs, evenly distributed energy, superior grinding media and a centrifugal grinding flow, it can have much more power than equivalent ball or tower mills.  What’s more, less residence time is required, so there’s less wasteful regrinding and the IsaMill™ is far more energy efficient and cost-effective. 

Same size as a HIG 

The IsaMill™ footprint is roughly the same as a HIG mill, since both require access areas. However the IsaMill™ requires less in civil works and does not require working under suspended loads.

More consistent product size 

IsaMill™ creates a more consistent product size because of the staged grinding process and horizontal layout. This means the product is more consistent and doesn’t need re-processing.

100% Accurate estimates and scale-up

When we model and scale up your IsaMill™ from sample tests, we’ll be able to assure you of product size or energy efficiency written into a performance guarantee.  It means you avoid flowsheet fails.

Now in more sizes

IsaMill™ now comes in the M7500 size, comfortably addressing the 1600-2300 kW range of power draw.  It’s also available in M15,000 and M20,000 for high throughput applications.

When we model your IsaMill™ from tests, we’ll be able to assure you of product size or energy efficiency written into a performance guarantee. It means you avoid flowsheet disappointments when you scale-up.
