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 …

This was developed into the first 'stirred ball mill' by Klein and Szegvari in 1928 . This prototype was refined into the Attritor mill, a low tip speed (3–5 m/s ) vertical pin mill which has been produced in various forms by Union Process since 1946 . Several other stirred media mill designs have been developed over the subsequent ...

(Stirred mills can produce product down to 7 microns). A comparison chart for grinding a pyrite concentrate with a ball mill (9 mm balls) and a stirred mill (2 mm sand) shows a decrease in net energy from about 44 to 24 kWh/tonne when producing a 20 micron product and going from about 80 to 30 kWh/tonne when producing a 15 micron product.

2. History of development and different mill designs Originally, tumbling ball mills were often used for wet fine and ultrafine grinding. But since the power consumption of tumbling ball mills is limited by the number of revolutions at which the grinding media are centrifugated at the chamber wall, the power density is relatively small.

Abstract The stirred ball mill (SBM) method is a common method applied in large-scale sludge disintegration. Many reports focus on the disintegration results of sludge or the influence of parameters on the anaerobic process of treated sludge, but there have been few studies on the mechanism of sludge disintegration by SBM. This study focused on the mechanism of sludge …
