    Crushing Properties Of Coal 2 Binary Coal Blends

    Mar 11 2021 The Hardgrove grindability index HGI of binary coal blends is determined. The blends contain coal of different metamorphic development in different proportions. Mathematical formulas permit prediction of HGI for a coal blend on the basis of the grinding indices for its individual components. For a binary coal blend with separate preparation of the components HGI is found to exceed the .
