Chen et al. [8] showed for an oscillatory ball mill that the median particle diameter d 50 (and also other percentiles such as d10 and d90) were well fitted by Rittinger's model for the grinding of DLactose from 450 to 150µm. For experiments on spruce saw dust on the same type of mill, Karinkanta et al. [9] showed, however, that d 50

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 ...

Grinding iron ores in conventional ball mills involve a considerably high consumption of metallic media, resulting in high operating costs. In the case of compact itabirites, the high silica content increases such consumption, potentially exceeding the costs associated with electric power consumption in industrial operations. This paper presents research conducted to assess the use of compact ...
