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.Email:[email protected]
Rotary Kilnbelongs to building material equipment, according to different materials, which can be divided into cementkiln, metallurgy chemicalkilnand limekiln. Cementkilnis used for making cementclinkerand there are dry and wet methods to make cementclinker.
There is no second wind in the process of calcination of white cementclinker rotary kiln, therefore, it can only through increasing the wind speed and the air flow of first air to increase the burning velocity. If the amount of primary air in therotary kilnis 3000-6000 cubic …
The Air-Quenching shaking grateClinker Coolerwas developed more than 20 years ago as an improved heat recuperating cooler for use withrotary kilns. It was designed to air quench and cool large quantities of hotclinkerrapidly, and to recover and return to thekilna major portion of the heat from theclinker.
The damage of the refractory lining of therotary kilnoften affects the continuity of production. It is one of the common equipment accidents. The causes of the defects include design structure, refractory quality, masonry quality and operation and maintenance.
AGICO Cement is a cement equipment manufacturer from China supplies various cementkilnswith rich experience and high quality. We are specialized in shaft verticalkiln, cementrotary kiln, and related cement equipment in theclinkerplant. Based on large production capacity and rich experience, we provide you with a full range of customization, manufacture, and after-sale service.
In its simplest form, therotary kilnis a tube up to 200 meters long and perhaps 6 meters in diameter, with a long flame at one end. The raw feed enters thekilnat the cool end and gradually passes down to the hot end, then falls out of thekilnand cools down. ... After cooling, theclinkermay be stored temporarily in aclinkerstore, or it ...
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.
KilnSpeed should be such that volumetric loading is within the range 10-15% and heat transfer is maximized. Pre-calcinerkilnsgenerally rotate at 3.5-4.5 rpm. Under normal conditions,kilnshould be run with as high rpm as possible. Higherkilnrpm improvesclinkermineralogy and grindability.

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 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.
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.
