A precalciner kiln system is the basis for this study. It normally consists of a preheater, a precalciner (also known as a calciner), a rotary kiln and a cooler. The kiln feed (i.e. the raw meal) is heated in the preheater and then sent to the precalciner where typically 85-95% of the calcination takes place. Calcination is the process of

The precalciner system is a suspension preheater in which, in addition to the kiln flame, extra fuel is burned in the base of the preheater. The first kilns of this kind operated in Japan in the late 1960s. These systems allow more thermal processing to be

A development of this process is the 'precalciner' kiln. Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%

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.
