Fossil Fuel Handling Encyclopedia of Life Support Systemsgas and oil is that they can be transported by pipeline directly from their source of supply or delivery. Coal, on the other hand, is not so conveniently transported and is usually delivered intermittently, resulting in a need for longerterm storage facilities. The coal itself, when utilized in large steamgenerating units, must be pulverized to aBall mill WikipediaChineseThe ball mill is used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out either wet or dry but the former is performed at low speed. Blending of explosives is an example of an appliion for rubber balls.Working&ensp·&ensp
