Investigation into the applicability of Bond Work Index
2015-10-15 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.

Grindability an overview ScienceDirect Topics
Grindability index is a measure of the ease of grinding of a given feed. Utility industries use the Hardgrove grindability index (HGI) to express this parameter. In the direct cofired system, the existing mills designed for coal are used for grinding the cofired biomass. So for a given mill, given rotation, and energy input, it is necessary to
