Clinkeris produced by sintering limestone (calcium carbonate) and clay (alumino-silicate) at elevatedtemperatures. The productionof clinkerinvolves the feeding of the raw meal into thekiln, where first the calcination of calcium carbonate takes place and then the resulting calcium oxide is burned at hightemperaturestogether with silica, alumina and ferrous oxide to formclinker.
[email protected]Cement kiln dust (CKD) is an industrial waste material collected from cement kiln exhaust gases during Portland cement production. In the production of Portland cement, clay and calcium carbonate are finely ground, mixed and calcined at1450 °C. During this process, calcium silicate is the main product formed and a dust named CKD is generated.
