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.
An impact crusher is a piece of heavy construction equipment people can use to reduce the size of things like rock, waste concrete, and similar materials.
Hongxing cone crusher is used for crushing ores and rocks and the advantages are reliable structure, high efficiency, easy adjustment and economy.
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.
Roll crusher is a crushing machine researched and manufactured by our company for coarse crushing.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
The convery belt is mainly composed by the expansion cylinder on both ends and the closed belts tightly knotted on them.
This series of jaw crusher belongs to stone crushing equipment which is widely used in the works of metallurgy, mining, cement, chemistry, refractory and ceramics as well as highway construction and water conservancy.
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 ...
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.
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.
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.
Operation of arotary kilnprovides many challenges. You have a very large and heavysteel cylindercontaining 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.
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.

in arotary kilnat temperatures around 4482 degr ees Celsius to formclinker. Theclinkernodules are then ground with about 3 % gypsum to produce cement with a fineness typically of
The Air-Quenching shaking grateClinkerCooler was 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.

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...
