Mar 12, 2018 The larger energy consumption in those investigations might be largely explained by low feeding rates and low grinding efficiency that is defined as the ratio of net SEC to total SEC. Fig. 3 Actual, corrected, and net specific energy consumptions SEC for FHRs compared to those for scots pine obtained under constant power 15
Dec 18, 2013 Fine grinding, to P80 sizes as low as 7 m, 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 mills energy budget.
