Energy Use of Fine Grinding in Mineral Processing

Dec 18, 2013· Finegrinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. Thisgrindingis typically done using stirred mills such as the Isamill or Stirred Media Detritor. While finegrindingconsumes less energy than primarygrinding, it can still account for a substantial part of a mill’s energy budget.
