Reactions in the cement kiln - clinkering

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.
