Hardgrove Grindability Index - Wikipedia

Hardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill. As grindability depends on many unknown factors, HGI is determined empirically using a sample mill according to the following procedure:

Based on the coal samples that have been tested thus far, HGI is a good predictor of the quantity of respirable dust that will be generated in a plate mill. The Wharton seam, an anthracite, produced the least amount of respirable dust while the Upper Freeport, a medium volatile bituminous, produced the most. It, however, cannot be generalized that a mine in an anthracite seam will be less dusty th
