The grindability of coal is important for entrainedflow gasifiers, which require pulverized coal for dry feeding systems or coal with a wide range of particle size distribution for slurry feeding systems. Because grinding is an inefficient process, choosing coals that are easier to grind can increase the overall efficiency of the process.
