Cement Plants: Coke

Coal-derived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century. Coal could not be used in static kilns in which the fuel is fed in with the raw material, mainly because, during the gradual heat-up of the charge, the fuel's volatiles are lost without ignition, so wasting up to half the fuel's calorific value. Burning coal ...

Cement Analysis and Production Information Thermo

While the cement production process before the kiln is focused on the elemental make-up and proportions of the raw materials, after the clinker is produced, the focus shifts to the molecules these elements form. As an example, Iron (Fe) is present in the raw mix and is required in a certain proportion in the raw mix, but the same iron in clinker can be present as Fe2O3, FeO or Fe3O4, the ...

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 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. Preheating of raw feed increases the energy efficiency of the kiln as the material is 20-40% calcined at the point of ...
