The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills energy efficient grinding machines. Vertimill® energy savings can range from 30% to greater than 50% compared with traditional mills, and the SMD energy savings can be far greater than 50% of ball mill energy in fine grinds.

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.
STIRRED MILLING TECHNOLOGY Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in between each
