Crushing and grinding account for upwards of 50 of mine site energy consumption and up to 3 of all the electric power generated in the world iRing Inc is the lead partner within The Paradigm Shifters and has coordinated the effort with proposal partners to respond to the challenge it said.
Energy of crushed kernels the sum of crushing energy and grinding energy ranged from 47 6 to 100 5 kJ183kg1 and from 44 6 to 85 3 kJ183kg1 for hard and soft wheat respectively In addition the other grinding energy indices confirmed that crushing of kernels prior to hammer mill grinding considerably reduced the grinding energy requirements.
Dec 18 2013018332Fine 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.
Energy with associated costs A substantial portion of this energy is expended in crushing and grinding Most particularly energy consumption in grinding is large The reason is that the change from feed size to product size achieved in grinding is typically much greater than in crushing.
