11.6 Portland Cement Manufacturing

1971-8-17  Cement raw materials are received with an initial moisture content varying from 1 to morethan 50 percent. If the facility uses dry process kilns, this moisture is usually reduced to less than1 percent before or during grinding. Drying alone can be accomplished in impact dryers, drum dryers,paddle-equipped rapid dryers, air separators, or autogenous mills. However, drying can also beaccomplished during grinding in ball-and-tube mills or roller mills. While thermal energy for dryingcan be supplied by exhaust gases from separate, direct-fired coal, oil, or gas burners, the most efficientand widely used source of heat for drying
