Some of the major findings from the study were as follows. HPGR energy consumption (kWh/t) was 38% of the ball mills. With all the different auxiliary equipment, HPGR total circuit energy usage was still less than 50% of the ball mill circuits. Fines removal from HPGR feed increased grinding efficiency in the compression zone by 25% to 30%.

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 ...
