to 2.20) and on coarse to fine coal separation. HARDGROVE GRINDABILITY TEST The Hardgrove Grindability test is a measure of coal’s resistance to crushing and attempts to reproduce the effects of continuous coal pulverization in a mill. A 50-gram sample of prepared coal of uniform size range is placed inside a grinding unit. The unit undergoes a
