The dry material is pulverized and fed to the rotary kiln. Further drying, decarbonating, and calcining take place as the material passes through the rotary kiln. The material leaves the kiln as clinker, which is cooled, ground, packaged, and shipped. For the wet process, a slurry is made by adding water during the initial grinding.

In the wet process and long dry process, all of the pyroprocessing activity occurs in the rotary kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter.
Dry Rotary Kiln overview. The cylinder body of the rotary kiln is rolled up by a steel plate. The cylinder body is lined with refractory lining and has a specified gradient with the level. It is supported by three-wheel belts on each supporting device. A large ring of teeth is fixed on the inner cylinder body of the span near the wheel belt at ...

In this kiln there are 3 different zones shown in fig. below Cement Manufacturing Process Flow Chart (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is directly fed into the kiln which has more amount of water.
A rotary kiln is a physically large process unit used in cement production where limestone is decomposed into calcium oxide which forms the basis of cement clinker particles under high temperatures. The modelling of rotary kilns are well documented in literature.
In the subsequent half century, efficient dry process kilns have almost completely displaced slurry-fed kilns. The pioneering was done by Blue Circle, who had eight dry process kilns in operation before the start-up of Tunnel's Padeswood A3 in 1966. The types of dry process kilns fall roughly into four categories: Long dry kilns Lepol kilns

With the arrival of rotary kilns, cement manufacturing processes became sharply defined as wet process or dry process. In the Wet Process, the kiln system is fed with a rawmix in the form of a liquid slurry, typically containing 30-50% of water by mass. In the Dry Process, the kiln system is fed with a rawmix in the form of a dry powder.
They are mixed either dry (dry mixing) or by water (wet mixing). 3) Prepared raw mix is fed into the rotary kiln. 4) As the materials pass through the kiln their temperature is rised upto 1300-1600 °C. The process of heating is named as "burning". The output is known as "clinker" which is 0.15-5 cm in diameter. 5) Clinker is cooled ...
