    In fact, the average crystal size of these abrasives are submicron, less than 1 µm, while that of fused alumina is about 200 µm. MSB has a microfracturing capability that results in self-sharpening characteristics, as well as high fracture toughness. Grinding wheels containing MSB abrasives can therefore demonstrate excellent grinding

  • Energy Use of Fine Grinding in Mineral Processing

    Dec 18, 2013· 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.
