IV. Coal Slurry Pipeline and Unit Train Systems
Coal is assembled from a mine or group of mines at a single point where mixing, cleaning, DESCRIPTION or other beneficiation may take place, and where the slurry is prepared. Preparation begins with impact crushing followed by the addition of water and further grinding to a maximum particle size of oneeighth inch. More water is then added to form a mixture that is about 50 percent dry coal .
