Figure 1 demonstrates the need for stirred milling to reduce power consumption for fine grinding of a pyrite concentrate. A grind P80 of 12 microns requires over 120 kwh/t in a ball 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 ...
