Reactions in the cement kiln - clinkering

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. In the more modern pre-calciner kilns, the feed is calcined prior to entering the kiln.
