    Coal in the cement industry

    Therefore, coal plays an important role in the manufacturing process of cement. Based on the 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.

    What is the use of coal in the cement manufacturing

    Coal is used to burn raw material to clinkering temp. i.e 1450 degree centigrade. Low grade coal can be used for cement manufacturing but it will need high grade of limestone for good quality cement. you can say low grade coal need high grade limestone and high grade coal need low grade limestone. 5.6K views View 4 Upvoters
