  • An assessment of grindability index of coal

    2002-4-20 · Therefore, high-moisture coals with less density and higher volume will get more crushing energy. So weight of the undersized material produced in unit time will be more resulting in higher HGI compared to low-moisture coal. So HGI of harder material like high-moisture coals will be apparently high, though the truth is contrary.
