Cement Kiln an overview ScienceDirect Topics

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 at 1450 °C. During this process, calcium silicate is the main product formed and a dust named CKD is generated.

Parametric Studies of Cement Production Processes

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.

Beneficial Uses of Cement Kiln Dust IEEE Conference

Cement manufacturing is a critically important industry in the United States and throughout the world. In 2006, U.S. cement plants produced 99.8 million metric tons of cement. Worldwide production accounted for about 2.5 billion metric tons. As with most large manufacturing industries, by-product materials are generated. These industrial by-product and waste materials must be managed
