Comparison of intergrinding and separate grinding for the

May 01, 1999· For cements containing blast furnace slag, unlike the natural pozzolan-incorporated cements, intergrinding consumes more energy than separate grinding to reach 3500 cm 2 /g Blaine fineness. However, the lower energy-consuming separately ground P + S cement still shows lower strength values than higher energy-consuming interground PS cement.

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. Overall energy use and media
