of a rotary kiln calciner. Advantages of the rotary kiln approach include: • drying and calcination in the same piece of equipment • no raw material grinding required. (feedstock only has to be sized to 50mm) • existing, running or decommissioned equipment can be adapted for clay calcination, which fast tracks a calcination project execution
Rotary Kilns and Dryers
Rotary kilns come in two different types: Direct fired rotary kilns — Consist of a steel shell lined with a protective brick or castable lining to withstand extreme temperatures. Indirect rotary kilns — Unlined kilns with shells made from a temperature-resistant alloy rather than steel. Rotary Dryers. Rotary dryers, on the other hand, dry ...
Reactions in the cement kiln
The decomposition products react with lime to form intermediate compounds which in turn form other compounds as clinkering proceeds. Water evaporation In wet-process kilns, and their derivatives, water must first be driven off. In a wet-process kiln, calcining takes place after the water has been driven off, about a third of the way down the kiln.
