According to Moema et al. (2009), in some instances, media wear can constitute up to 40–45% of the total cost of comminution. An estimated consumption of steel grinding media of around 600,000 tons p.a. in the 1980s already gives an indication of the scale of the problem ( Malghan, 1982).

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

In recent years, stirred mills have been preferred in fine grinding and ultrafine grinding units, with high grinding efficiency and energy savings. For this reason, more attention has been paid to the effects of stirred mill types, tip speed, solid concentrations, and media size on specific energy input, particle size distributions, and

Abstract. The grinding process in ball mills is notoriously known to be highly inefficient: only 1 to 2% of the inputted electrical energy serves for creating new surfaces. There is therefore obvious room for improvement, even considering that the dominant impact mechanism in tumbling mills is a fundamental liability limiting the efficiency.

Energy consumption and dissipation are discussed, leading into a thermal model for grinding. The analysis developed over many years applies to shallow-cut conventional grinding processes and also to deep grinding processes. Energy analysis provides insights into the grinding process and suggests avenues for process improvements.
