stages. The result is the multi-stage cyclone preheater as it is generally applied in modern cement plants. In the early years, one and two stage systems have been installed with long kilns, often to avoid problems caused by circulating phenomena. A large number of plants are equipped with four stages; the majority of them were built before 1990.
