Hardgrove Grindability. Hardgrove grindability is a measure of the relative ease with which a coal sample can be pulverized or ground to smaller sizes. All mined coals need to be ground to very small sizes (often powder size) before being utilized. For example, most steam coals (used to generate electricity) are ground to 60 mesh (250 microns ...
