Energy for the comminution of raw coal in power plants consumes nearly 0.5–1% of the gross power generation ( Shi et al., 2015 ). This proportion would increase to over 55% in the mineral processing plant ( Narayanan, 1987 ). In this case, selection of alternative grinding devices is mainly based on the energy saving.
