It has proven to be significantly more energy and metallurgically efficient than conventional ball mills and tower mills (Larson et al., 2008, Larson et al., 2011). Ongoing efforts by Glencore Technology to further improve the energy efficiency of the IsaMill™ have resulted in a new IsaMill™ shaft spacer design.
The IsaMill™ reduces the energy, media and capital costs of grinding. It's incredibly efficient and intense. It focuses only on the particles that need grinding. The IsaMill™ produces greater power intensity than ball or tower mills. Today's IsaMill™ is also light.
Therefore, its foundation can be a concrete floor slab designed for dead load only, whereas a cylindrical ball mill requires a reinforced concrete submat with a minimum of two times the mass of the rotating parts. Regrind Mill Work Index. The operating work index was also calculated for all available full scale mill data and is shown in Figure 16.
The IsaMill™ has real-world success in 143 metalliferous installations across 23 countries. It's the world's only horizontal fine-grinding mill, so it avoids short-circuits, is highly efficient and gives the highest availability. …
The IsaMill is a horizontal high speed stirred mill that operates with very high power intensities (up to 350 kW/m3). In comparison, the power intensity of a ball mill is about …
In late 2005, a 2.6MW M10,000 IsaMill™ was commissioned at Kumtor, treating the regrind ball mill discharge to a product sizing of 80% passing ~10 µm. Figure 6 illustrates the before and after flowsheets. ... Replacement of Kumtor Ball Mill with IsaMill™ During Ball Mill Maintenance.
An IsaMill will soon be trialed to replace a ball mill regrinding concentrate before gold cyanidation. The ball mill is currently consuming 10t/day of steel media, which enters leach feed. This will provide a future case study of the impact of inert grinding on leach performance and reagent consumption.
and regrind ball milling became a standard flow sheet inclusion in the latter part of the previous century and is still common today. The modern high intensity stirred mills (such as the IsaMill) further extend the energy benefits of this technology by using higher agitation speeds and smaller media particles. Media selection has a major ...
The modern high intensity stirred mills (such as the IsaMill) further extend the energy benefits of this technology by using higher agitation speeds and smaller media particles. Media selection has a major influence on mill parameters such as energy efficiency, internal wear and operating costs.

Depending on the size range a Vertimill (), a stirred media detritor () or an IsaMill (Xstrata) is typically used. All three use a different motion than a tumbling mill and as a result each has their own laboratory test for scale up.
The mills may also be oriented horizontally (IsaMill) or vertically (the remainder). Vertical mills fed from the bottom (HIGmill) will tend retain the beads and coarser (oversized) feed particles, provided they settle faster than the rise rate up the mill. Horizontal mills like the IsaMill use a centrifugal
