IsaMill, a fine grinding technology that has made a name for itself on the market over the last 25 years as the world's only horizontal fine-grinding mill, always had advantages.

The IsaMill separator has successfully operated with a wide variety of medium. types, such as silica sands, river gravel, smelter slag, run-of-mine ore fractions and steel shots, with sizes ...

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.

The laboratory scale IsaMill consisted of a horizontal milling chamber, drive motor and 6 disc radial impeller. The mill was fitted with a. 4.0 kW variable speed drive and Yokogawa power meter to determine the specific energy requirements of each grind. A diagram of the laboratory ISAMILL set up is shown in Figure 5.

Full scale ball mill versus full scale IsaMill. The Kumtor Gold mine of Centerra Gold is located in the Tien Shan mountain of the Kyrgyz Republic, and produces more than 500,000 oz gold per year. In October 2005 Kumtor commissioned a 2.6 MW IsaMill to fine grind leach feed to increase gold liberation and recovery (Kazakoff et al., …

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a …

How it works. Eight consecutive grinding chambers, patented product separator and short residence times means the mill constantly delivers sharp product size distribution without external classification. The IsaMill™ is a closed mill. Slurry travels through the mill in a 'plug' flow pattern through consecutive grinding discs.

The large scale of the IsaMill™ makes that efficiency available to mainstream grinding. The high energy efficiency of stirred mills compared to ball mills is well understood. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century.

The IsaMill tests were performed at another copper mine, which has the flowsheet depicted in Figure 3. As indicated on t he illustration, the mill aimed to process the cyclone underflow stream to replace the ball milling application. Figure 3.
