  6. Cement kiln - Wikipedia

    en.wikipedia.org/wiki/Cement_kiln

    Cement kilns are used for the pyroprocessing stage of manufacture of portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity ...

  7. Cement clinker - Wikipedia

    en.wikipedia.org/wiki/Cement_clinker

    Portland cement clinker (abbreviated k in the European norms) is ground to a fine powder and used as the binder in many cement products.
