Get PriceThe core of the pyroprocess of each modern cement kiln is the preheater. Most substantial thermo-chemical reactions of the cement process occur in the riser ducts and in the calciner(s) and certainly in the sintering zone of the kiln. Modern suspension preheater kilns usually have 1 or 2, in a few cases also 3 strings with 4 or 5 stages.
