  • YGP Index of Coal - bulk-online

    2009-9-10  Coal grind ability index HGI (YGP) indicates the ease for grinding coal.. The bigger of grind ability index, the easier to be grinded. Hardgrove Grindability Indices indicate that how hard the the coal is. The variation of HGI of each zone of 40 -60 means that the grindability is poor.
