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 a simple classification of lignites with different grindability an impact grindability index is introduced in analogy to the Hardgrove Index (HGI). This impact grindability index is to be used by the manufacturers and operators of lignitefired steam generators as an index for the grindability of lignite in beater wheel, beater or fan mills.
