In a wet-process or preheater system without a pre-calciner, most of the calcination takes place in the rotary kiln within a moving mass of feed. ... Evaporation of volatiles Volatile phases in the cement kiln are principally alkali sulfates, with a much smaller proportion of alkali chlorides. As the part-burned feed approaches the burning zone ...

The kiln is the heart of the cement plant. Inside, temperatures reach over 1500 °C as raw materials are transformed into clinker. They are also big, reaching diameters of 6 m or more and lengths of over 100 m. To operate in such conditions, components must be well designed and flawlessly made. No easy task. But one in which we at KHD have a long and distinguished …

In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.

The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot …

The partly calcined material then falls down a chute into the rotary kiln where final clinkerization takes place. Because the kiln feed is already partly calcined before it enters the kiln, the rotary kiln itself is only about one-third the usual length. ... THE PRECALCINER KILN. Roughly 15 years ago, Japanese cement manufacturers were ...
