In all of these industries, gypsum is needed in ultrafine ground form [2]. Grinding has been utilized in manufacturing fine and ultrafine powders for the development of new materials and for improving product quality. For a long time, grinding processes, especially in ball mills, have been subjected to statistical and kinetic analysis [3], [4].

This means that when the sun wheel rotates once, the grinding jars rotate twice in the opposite direction. Figure 4. In the planetary ball mill, centrifugal and Coriolis forces permit grindings down to the submicron range. The result of grinding of alumina (Al 2 O 3) at 650 min 1 in the PM 100 is shown in Figure 5.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

Ultrafine grinding must be carried out using specialised equipment, specifically stirred media mills. Due to geometric limitations, tumbling ball mills have a small energy intensity, limited by the number of revolutions at which the grinding media is centrifuged in the mill wall (Celep et al., 2011). Attrition stirred mills are widely applied ...
