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. Also, the sampling tests indicate that this difference is over 25%, which demonstrates the MPS type VSP shows a better grinding performance.

The Hardgrove grindability index (HGI) serves as a predictor of the pulverization behavior and, by extension, the efficiency of combustion. For example, Fitton et al. demonstrated that a 53 HGI coal requires 2.5-times the number of revolutions in a ball mill than a 110 HGI coal to achieve 80% passing 200 mesh. Similarly, Lowe projected a 1% loss of mill throughput for each decrease of 1 HGI unit.

• In pulverized coal combustion, the ratio of coal to carrying gas is usually in the range of y = 0.5-0.6 kg/kg. • Assuming a coal density rc = 1.5 x 103 kg/m 3, and the density of the carrying gas as rg = 0.9 kg/m 3, the volume fraction of the coal can be shown to be very small, 0.036 % .
