type of coal used by cement plants

Cement Plants: Coal

London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning. Per tonne of clinker produced, consumption was ...

Coal in the cement industry

composition of raw feed a wide range of coal is used. In a cement plant two systems of coal firing are used, namely, a) Direct firing and b) Indirect firing. In direct firing system, coal is milled on line and is directly fed to the kiln. The primary air is used to dry the coal. High moisture coal
