  • Cement Plants: Coal

    Bituminous coals make the best coke and are in any case the most common, and these are most often used in the cement industry, although steam coals are occasionally used. When burning a pulverised fuel, higher volatiles are preferred because they speed up ignition and allow a coarser grind to be used.

  • Coal cement World Coal Association

    Clinker is mixed with gypsum and ground to a fine powder to make cement. Coal is used as an energy source in cement production. Large amounts of energy are required to produce cement. It takes about 200 kg of coal to produce one tonne of cement and about 300-400 kg of cement is needed to produce one cubic metre of concrete.

  • 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 ...
