Hardgrove Grindability Index (HGI) Mining SGS

The Hardgrove Grindability Index (HGI) is a measure of coal’s resistance to crushing. Grinding studies, and the resulting HGI, allow many different types of coal users to evaluate how coals will perform in their mills, allowing them to estimate grinding power requirements and throughput capacities.
