  • Crushing Circuit an overview ScienceDirect Topics

    17.7.1 Crushing and grinding. Coal hardness is a key selection criterion for PCI coals. The cost of grinding and of mill productivity is related to the hardness of coal as measured by the Hardgrove Grindability Index (HGI). A high HGI is indicative of coals which are easier to grind, consume less power and have greater mill throughputs.
