Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. The year 1948 saw the successful application of DuPont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of stirred mills spanning

Figure 10.1 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.
