Pyroprocessing and Kiln Operation
Pyro-processing section is considered to be the heart of a cement plant as actual cement clinker production takes place in kilns. The size of a cement plant is determined based on the pyro-processing section and the sizes of all other equipment are determined to match pyro-processing. Cyclones are basic units in a preheater system.
