    Nevertheless, grinding to a finer size would bestow major advantages both from the point of view of combustion as well as slurry handling and, above all, stability. Cochran and Sell (1979) have presented a convincing case for grinding coal significantly finer, to the ultrafine size with a median value of perhaps 15 μm and 90% -325 mesh. They
