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.

Portland Cement Kiln Dust Reprocessing
X-ray diffraction and compression tests showed that satisfactory cement could be made from cement kiln dust. ASTM standard C-150 specifies that total alkali content of cement calculated as weight percent Na2O + 0.625 x K2O must be below 0.6 pct. All melted and sintered cement kiln dust cement had an alkali content of 0.094 pct or less, almost an order of magnitude below the ASTM standard.
Taiheiyo’s bottom ash washing and desalination …
Chlorine content – which is harmful to both kiln operation and cement quality – is as high as 10-20 per cent in incineration fly ash. Recycling technology turns the fly ash into a cement raw material by washing the ash and removing the chlorine (Figure 1). In contrast, incineration bottom ash, which contains a chlorine content as low as 1-2 per cent, only requires metal removal for use as ...

The cement kiln
Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the hot end where it eventually drops out and cools ...
