In this experiment we processed limestone using two different media sizes: mm zirconiasilica grinding media (SAZ) and mm SAZ. We can see that rapid par ticle size reduction occurs and the curve plateaus at around μm for the nominal media and the curve starts to plateau around to 2 m for the 2 mm μ nominal media.

Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.

The vertical mills have a large vertical doublehelical steel screw agitator located centrally in a vertical cylindrical shell. The agitator rotates and stirs the media while simultaneously lifting and circulating it throughout the mill (Morrison et al., 2009).These mills have found applications in regrinding circuits during the last few years because on their higher efficiency and their small ...

Figure 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.
