Stirred Mills – Ultrafine Grinding - ScienceDirect

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.
