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.

The grinding rotor configuration and the whole chamber geometry have been optimized for efficient energy transfer to the bead mass, internal circulation and classification. Make-up grinding media is fed to the mill together with feed slurry or from the top. The …

Abstract This paper is focused on the grinding and dispersion of TiO2 in a stirred bead mill.
