Stirred Mills Ultrafine Grinding ScienceDirect

2016-1-1  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.

What is the difference between a SAG mill and ball mill?

Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material. In tower mills, there is no cascading action as in standard grinding mills. Stirred mills are also common for mixing quicklime (CaO) into a lime slurry.

Abstract Studies were made of the grinding kinetics of chromite ore in a stirred ball mill. Grinding tests were carried out using material in discrete size ranges (−53 + 38 μm and −38 + 25 μm) and for material conforming to a natural spread of sizes (−100 μm). Tests conducted on the discretely sized material were used to establish the breakage function for the ore.
