2012-11-8 Coal in the cement industry Cement manufacturing consists of raw meal grinding, blending, pre calcining, clinker burning and cement grinding. Limestone, CaO, SiO2, Al2O3 and Fe2O3 are crushed and milled into a raw meal. This is blended and preheated in a preheater cyclone.
Read MoreAnthracite coal can be used as a smokeless fuel in domestic and industrial contexts. In any case, while many coal types are often painted with the same brush, there’s definitely more than one type of coal out there. Getting to know the difference between these coal types is key for energy investors evaluating companies and projects.

More than 30 raw materials are known to be used in the manufacture of portland cement, and these
Read MoreCoal is used for heating the raw materials at 1450 degrees centigrade to turn into clinker. The grade of coal supplied in the cement manufacturing industry depends on the grade of limestone used in the cement manufacturing process. If the limestone used in the cement manufacturing process is of high grade then low-grade coal is used and vice versa.
