The grinding experiments were executed in two different types and sizes of mills to consider mill specific effects: One was the LM4 IsaMill TM from Netzsch, the other one the PM1 from Drais. The LM4 has an internal deflector wheel and its volume is around L. Six perforated discs have been used with a distance of 35 mm.
mill using 9mm balls, but only 40 kwh/t in an IsaMill with 2mm media. The curve demonstrates the difference between "conventional" grinding and fine grinding. The Bond Work Index is developed for the flat "A" section of the curve, but does not apply to the exponential increase in grinding energy after the "knee", section "B".
This laboratory work presents a study of the effect of ultrafine grinding on the gold recovery of a highly refractory gold concentrate. The particle size of the concentrate was P80 = 46 µm and the main species present were quartz (%), dolomite (%), pyrite (%), arsenopyrite (%) and 112 g/t gold. After optimizing hydrated lime and lead nitrate additions, standard cyanidation ...
These IsaMill™ with sizes from up to 20 m 3 is a horizontal stirred media mill with a perforated disc geometry and a classifier wheel at the product outlet. The IsaMill™ keeps the grinding media away from the discharge with its internal classifier and implies a counteracting current to the drag forces caused by the suspension flow.
1.. IntroductionIsaMill is a highspeed stirred mill developed by Mount Isa Mines (Xstrata) in Australia for fine and ultra fine grinding at an industrial scale [1].Comparing with the conventional grinding mills such as ball mills and tower mills, IsaMill can significantly reduce comminution circuit energy cost and grind mineral particles to as fine as 7 μm [2], [3].
Traditional finegrinding mills in mineral processing rely on the use of steel medium for particle size reduction. The IsaMill (a horizontal stirred mill with a 3,000L net chamber volume and a ...
IsaMill Ultrafine Grinding | 226 followers on LinkedIn. IsaMill™ horizontal milling for efficiency, safety, product size and availability | The IsaMill™ has realworld success in 129 metalliferous installations across 21 countries. It's the world's only horizontal finegrinding mill, so it avoids shortcircuits, is highly efficient and gives the highest availability.
The IsaMill is an energyefficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of the Glencore Xstrata group of companies) and Netzsch Feinmahltechnik ("Netzsch"), a German manufacturer of bead mills. The IsaMill is primarily known for its ultrafine grinding applications in the ...

The accuracy of this model is likely to be much worse than lab scale grinding tests such as the IsaMill signature plot method; although the fit in Fig. 3 looks good, it is a loglog plot, and so disguises the relatively wide spread of data points. However, practically it can be used to select appropriate operating conditions to trial in these ...
The scaleup procedures developed for the IsaMill were then compared against the full scale Century SMD's. The IsaMill M4 procedure accurately predicted the full scale Century performance on a P 80 basis. This is intuitively correct though the mills have different designs (horizontal versus vertical), essentially

Grinding media types Until 2005, all IsaMill installations have taken advantage of the technology's ability to use low cost, but relatively low quality grinding media such as silica sand, river pebble, smelter slag or fine primary mill scats (autogenous milling). Whilst the IsaMill produces high energy efficiencies
volume) were addressed. The most distinctive feature of the ISAMILL is its media separation system that enables slurry to exit the mill but prevents the grinding media from leaving the mill (Enderle et all, 1997). Since this time, the ISAMILL® technology has been implemented at several mining operations and undergone further development.
Abstract. IsaMill is a highspeed stirred mill that has been newly developed in the mineral industry for fine and ultrafine grinding. In this paper, a numerical model that is based on the discrete ...
