Figure shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.

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 20 kW/m3. The high power intensity enables the IsaMill to process fine particles at a high throughput that is essential for the economics of the minerals industry.
