Roller mill

For coarse reduction of grain a roller mill may have a significant advantage (perhaps as high as 85 percent) over a hammermill in terms of throughput/kwh of energy For cereal grains processed to typical sizes (600 to 900 microns) for the feed industry the advantage is about 30 to 50 percent

Energy Use of Fine Grinding in Mineral Processing

2013/12/18Fine grinding to P80 sizes as low as 7nbsp 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

Best energy consumption

However in pure energy efficiency terms the benefit of grinding power reduction is countered by the very high power required by mill fans In addition the absence of the heat generated in a ball mill and the high volume of air required by the vertical mill have required the provision of waste heat from cooler exhausts and/or auxiliary furnaces to dry raw materials and achieve a limited
