Hardgrove Grindability Index (Hgi) | Sgs

The coal fines are sorted and the quantity of coal less than a specified size is recorded and converted into a Hardgrove Grindability Index (HGI) value; Typical resulting HGI values lie between 30 (increased resistance to pulverization) and 100 (more easily pulverized).
