  • Field-scale investigation of pulverized coal mill power

    Twenty field-scale tests were conducted in a 28 MW pulverized coal power plant in Healy, Alaska, to examine mill power consumption in relation to coal grind size. The intent in this field-scale study was to verify if grind size truly impacted power consumption by a detectable amount. The regression model developed from the data indicates that grind size does impact mill power consumption, withEnergy Consumption in Mining Comminution ScienceDirect,2016-1-1 · Energy consumption occurs everywhere in the mining and manufacturing sectors.
