moisture content where coal produces dust

    Laboratory Methods for Predicting Coal Performance- moisture content where coal produces dust ,where dust can no longer be held on the surface of a coal particle The CMC is equivalent to the ASTM Equilibrium Moisture (8) or the maxirnum content of pore heldCoal - FoodTechInfoAnthracite is a clean, dense, hard coal that creates little dust in handling It is comparatively hard to ignite, but burns freely once started , With only half the volatile matter content of bituminous coals, burning produces less smoke; hence, it is sometimes called smokeless coal , total moisture content of a sample is ,.
