In Hardgrove test, grindability index is determined when a constant crushing pressure (29 kg) is applied over some constant weight of coal (50 gm) to grind it in unit time, and undersized material (below 74 μm) is weighed to calculate the index. Therefore, high-moisture coals with less density and higher volume will get more crushing energy.
