Though the particle size and feed rate of MPS type VSP are larger, the yield of −75 μm PF is larger and the PF P 80 is smaller if compared with those of E type VSP. The bigger HGI of coal ground by MPS type mill may lead to a 10%–15% difference in the yield of −75 μm PF in comparison with E type VSP.
