what type of coal used for cement

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 is not suitable for direct firing, as this has the effect of lowering the flame temperature and ...

Cement Plants: 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 around 0.5 tonnes of coke and 0.1 tonnes of coal. Coal could not be used in most static kilns because the fuel was loaded into the kiln with the rawmix, and in the process of gradually raising the temperature, coal would lose its volatiles - and ...

Summary: In this paper the use of coal, found at Jabba Taar and Jabba Khushk Khyber Pakhtoon Khwa, in cement manufacturing as a major fuel and its impacts on the raw mix and clinker parameters has been discussed. The maximum amount of coal for pulverizing with raw mix was found to be 10%`of the raw mix as calculated from the calorific value and the heat of clinkerization of coal. The coal ...

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 ...
