Energy Use of Fine Grinding in Mineral Processing

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

The link between operational practices and specific

An analysis during an energy audit at Wesfrob Mines Ltd (now closed) showed that the relationship between specific electricity consumption (kW h/tonne) and throughput for the total operation as well as for the separate crushing and grinding stages was inversely related (Doyle 1979) energy savings at the mill could be achieved either by increasing the amount of ore extracted from the mines or by reducing the
