one of the important parts of the cement production plant is the rotary kiln. that homogeneous corrected slurry is applied by nozzle spray on the upper end of the rotary kiln. rotary kiln is a 3m to 8m diameter steel cylinder, lined with fire resistance refractory materials, fitted on roller bearings and capable of rotating about its own axis at a designed speed.
the clinkers which are output from the rotary kiln are very hot hence they are first cooled by air in a countercurrent fashion. the clinkers are of size of about 5-10 mm. they are fed to grinders in order to grind them to reduce their sizes. the clinkers are fed into ball mill or tube mill along with powdered gypsum.
cement is typically made from limestone and clay or shale. these raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. this blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 c to 1500 c.
chemical reactions during cement manufacturing process. the reactions that take place (after evaporation of free water) between the reactants in the kiln phase of cement making process are as follows: clay decomposition: si 2 al 2 o 5 (oh) 2 → 2 sio 2 + al 2 o 3 + 2 h 2 o (vapor) kalsi3o8 (orthoclase) + 0.5 so 2 + 0.25 o 2 → 3 sio 2 + 0.5 al 2 o 3 + 0.5 k 2 so 4
cement manufacturing process phases. production of cement completes after passing of raw materials from the following six phases. these are; raw material extraction/ quarry. grinding, proportioning and blending. pre-heater phase. kiln phase. cooling and
china sunrise machinery (csm)is a professional cement equipment manufacturing enterprise, the main products are cement production line including: tube mill, rotary kiln, roller press, vertical mill, rotary dryer, suspension preheater.
kiln and kiln shells: - as a cement kiln manufacturers we manufacture all type of process equipments including vertical and roller kiln and shells - kiln shells is involved in the process of burning the raw mixture thereby resulting in the clinker.
the next development in the manufacture of portland cement was the introduction of the rotary kiln, patented by frederick ransome in 1885 (u.k.) and 1886 (u.s.); which allowed a stronger, more homogeneous mixture and a continuous manufacturing process.
the crushed rock is combined with other ingredients such as iron ore or fly ash and ground, mixed, and fed to a cement kiln. the cement kiln heats all the ingredients to about 2,700 degrees fahrenheit in huge cylindrical steel rotary kilns lined with special firebrick. kilns are frequently as much as 12 feet in diameter—large enough to accommodate an automobile and longer in many instances than the height
the main equipments used in this whole production line include the vibrating feeder, jaw crusher, impact crusher, cement ball mill lifer, preheating system, cement rotary kiln and packing machine and so on.

2-the rotary cement kiln. if you want to learn the basic principles of operation of a cement kiln, this is the book you should read. it is an excellent base for the training of the kiln operators, supervisors and production or process managers. it emphasizes what he calls the 27 kiln basic conditions.
the resulting raw mix is fed into a cement kiln which heats them to extremely high temperatures of about 1400 c to 1500 c. bulk material handling equipment, such as a rotary feeder in a cement plant, is used to transfer these raw materials and mix between points in the production process.
approximately 10–20% of the kiln feed can be suspended in the kiln exhaust gases, captured, and returned to the feed. other sources of dust emissions include the clinker cooler, crushers, grinders, and materials-handling equipment. when the raw materials have high alkali or chlo-ride content, a portion of the collected dust must
kiln phase. since clinker is a complex mixture of ingredients, it requires a multi-staged heat treatment, which is done in the kiln. the main part of the manufacturing process of clinker takes place in the kiln. the stages in the kiln phase are as follows:

optimizeit expert optimizer reduces cement manufacturers’ emissions in three distinct areas: • the burning of cement clinker in rotary kilns is controlled more efficiently, thus reducing the energy requirements of the process. this reduction in the energy consumption reduces the quantity of alternative exhausts emitted into the atmosphere.
wet process kilns. 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.
some refractory materials for rotary kiln sintering zone. magnesite-chrome brick. the magnesite-chrome brick has excellent corrosion resistance and spalling resistance. at the same time, it has high strength, so it is widely used in the sintering zone of cement rotary kiln.
cement kilns are used for the pyroprocessing stage of manufacture of portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. as the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture…
a cement kiln incinerator is an option that can be used to incinerate most hazardous and non-hazardous wastes. the rotary kiln type is the typical furnace used in all cement factories. rotary kilns used in the cement industry are much larger in diameter and longer in
