Ball mills are progressively used to grind the ores for particle size reduction and to liberate valuable minerals from the ores. The grinding of ore is a highly energyintensive process [1,2,3,4]. In this process, the size of the particle obtained depends on the energy consumption of the ball mill.

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 ...

Assisted by the impact and abrasion between media (steel ball, steel rod, gravel, ceramic ball) and ore, the grinding operation reduces the particle size in the mill [[1], [2], [3]]. To produce the qualified size and high liberation of granule for the subsequent separation is the primary objective of the grinding operation [4,5].

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 ...
