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.
