Geochemical partitioning from pulverized coal to fly

2020-11-1  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
