Energy Use of Fine Grinding in Mineral Processing | SpringerLinkDec 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.energy consumption for grinding,How do I reduce energy consumption in my grinding operation?Jun 1, 2016 . rying feed material prior to processing is the number one energy hog in a grinding operation. Any steps that you can take to reduce moisture — such as protecting your feed material from weather — will have a big effect on your energy use. Moisture has a cushioning effect and can cause particles to stick.
