# Mathematical Calculation For Cement Kiln

### Numerical modelling of flow and transport processes in a

Controlling the calcination process in industrial cement kilns is of particular importance because it affects fuel consumption, pollutant emission and the final cement quality. Therefore, understanding the mechanisms of flow and transport phenomena in the calciner is important for efficient cement production.

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.
