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.
Grindability an overview ScienceDirect Topics
Hardgrove Grindability Index (ASTM D409 Standard) Grindability is an important factor for the characteristic of the brittle raw materials by the design the mills. As grindability depends on many unknown factors, hardgrove grindability index (HGI) is determined empirically using a sample mill, according to the following procedure.

15-10-2015· The Hardgrove Grindability Index (HGI) test is based on Rittinger’s theory that “the work done in grinding is proportional to the new surface produced”,. The index varies from 20 to 110, with a lower HGI indicating a coal is harder to grind and more energy will be required to reach the required degree of fineness.
