Cement rotary kiln, also calledclinker kiln, can be divided into dry-processcement kilnand wet-processcement kilnaccording to the cement production technology. Dry-processcement rotary kilnis mainly used tocalcine cement clinker.
The found average difference in Heat required forclinkerformation between temperature 1338 °C and 1450 °C is 82.26 kJ/kg-clinkerrepresenting 2.23% of Total heat input are 3686 kJ/kg-clinker...
In therotary kiln, the carbonate is further rapidly decomposed and a series of solid phase reactions occur to generatecement clinker. After a series of chemical reactions, the high temperatureclinkerdischarged from therotary kilnis cooled by thecement clinkercooler.

Forclinker production, a mixture of clay, limestone, and sand is heated to temperatures near 1500°C. Thekilnandclinker coolerhave hot exhaust streams where waste heat could be recovered. Thekiln exhauststream, when no WHR is used, is at about 450°C.

Theclinkerdust particules carried back by the secondary air stream from theclinkerbed grate into the interior of therotary kilnalso play an important role on formation of these deposits.

In the diagram above of a precalcinerkiln, 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,clinkernodules and the finalclinkerminerals form.
It is the main body of arotary kiln(Retorting rotary kiln), usually 30 to 150 meters long, cylindrical, with 3 to 5 rolling rings in the middle. Thecylindersare mostly processed by the factory into 3~10 sections, which are welded by large trucks to the destination and welded.
Firing of cementclinker. In therotary kiln, the carbonate is further rapidly decomposed and a series of solid phase reactions occur to generate cementclinker. After a series of chemical reactions, the high temperatureclinkerdischarged from therotary kilnis cooled by the cementclinkercooler. To a reasonable temperature, while recovering ...
The cementclinkercalcination is an important step in the cement production process. It mainly occurs in cementkilnand can be roughly divided into six reaction stages, namely drying, preheating, chemical decomposition, exothermic reaction, sintering and cooling.

Arotary kilnis a steel round shell with refractory lining that rotates. This shell is rotated by a drive gear and electric or hydraulic drive system. The shell is supported on large bearings. There is a single large burner that heats the pellets up as they travel through thekiln. Annular cooler. An annular cooler is a turntable that holds ...
Operation of arotary kilnprovides many challenges. You have a very large and heavy steel cylinder containing substantial amount of material which is rotated with a drive system often having two motors. This means that the starting of thekilnrequires high toque that can be 2.5 times the full load torque.
