The history of pulverization date back as early as 1824 and was envisaged by Carnot in a coal fired engine. In 1890 Diesel made use of pulverized coal in his diesel engine. The pulverized coal firing was first developed in cement industry which then migrated to power and process industries. Pulverizing coal in boiler is an important factor the overall cycle efficiency.
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.
