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:

Grindability an overview ScienceDirect Topics

The Hardgrove Grindability test is commonly used to characterize the milling behavior of coals. The test, first conceived by Hardgrove (1931) and later modified to the current constant-weight test in 1951 (ASTM D409-71, 1971; ISO 5074, 1994c), attempts to mimic the operation of a continuous coal pulverizer using a batch process. As noted by Hardgrove (1931) and others (Roth et al., 1992; Hower, 1998) the
