Rotary kiln refers to rotary calcination kiln (commonly known as rotary kiln) and belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns, and lime kilns according to different materials processed. Cement kilns are mainly used for calcining cement clinker, which divided into two categories: dry process cement kilns and wet process cement kilns. Metallurgical and chemical kilns are mainly used for magnetizing roasting of iron ore-depleted ore in iron and steel plants in the metallurgical industry; oxidizing roasting of chromium and nickel-iron ore; refractory plant roasting high alumina vanadium ore and aluminum plant roasting clinker and aluminum hydroxide; And chrome ore powder and other minerals. Limekiln (ie active lime kiln) is used for roasting active lime and light-burning dolomite used in iron and steel plants and ferroalloy plants.
Cement rotary kiln belongs to the category of building materials and equipment, it is a kind of lime kiln. 0.5mm tolerance cement rotary kiln means that the allowable error of rotary kiln shell is within plus or minus 0.5mm.
Lime rotary kiln is also called roller rotary kiln. To make sure its air leakage coefficient is less than 10 percent, lime rotary kiln adopts advanced structure and reliable combined scale-like seal in both ends. It also uses composite refractory to reduce the loss of heat radiation.
Shaft kiln, just as its name implies, is a kiln with erected shape. Shaft kiln with modern new technology has environmental protection function, energy-saving function, high mechanization, and high automaticity. It also has the ability to turn waste into wealth.
The rank of countries alumina bauxite storage is Australia, The Republic of Guinea, Jamaica, China, and India. Rich reserves provinces in China are Shanxi, Guizhou, Guangxi, and Henan province. Generally, alumina bauxite is used to produce alumina or aluminum.
The data survey found that the price of AGICO groups rotary kiln will be about 600-1000 cheaper than the prices offered by the merchants in other cities. The reasons for the analysis are as follows:
It is the main body of the rotary kiln (rotary kiln), usually 30 to 150 meters long, cylindrical, with 3 to 5 rolling circles in the middle. Most of the barrels are processed into 3-10 sections by the factory, and then welded by large trucks to the destination.
On the contrary, the cooler and the preheater are devices that rapidly reduce the temperature of the rotary kiln after firing. It looks like a small rotary kiln, but the diameter is smaller and shorter.
It is also called preheater, which is a device for preliminary heating of materials by the waste heat of exhaust gas discharged from the rotary kiln before the materials enter the rotary kiln. Most of them are vertical structures.
Cement rotary kilns refer to cement rotary calcining kilns (sometimes called rotary furnaces). It is a pyroprocessing device used to heat materials to high temperatures in a continuous process. The kiln body is a cylinder vessel with a certain degree of tilt to the horizontal level. Raw materials are fed into the vessel from the upper end and moved to the lower end, being stirred and mixed relying on the inclination and rotation of the kiln. The kiln burner produces a lot of heat by burning fuel. This kind of heat is usually transferred to materials through flame radiation, hot gas convection, kiln brick conduction, etc., which causes the chemical reaction between raw materials and finally forms clinker.
Rotary kilns can be divided into cement kiln, metallurgical and chemical rotary kiln, lime rotary kiln and so on. Cement rotary kilns are used for calcining cement clinker in the cement plant, which can be divided into dry cement kiln and wet cement kiln. Metallurgical and chemical rotary kilns are mainly applied in the metallurgical industry. As for the lime rotary kiln, it is the main equipment for calcining active lime and light burned dolomite used in iron and steel plants, ferroalloy plants, calcium carbide plants, and magnesium metal plants.
The cement rotary kiln is mainly composed of cylinder, supporting device, drive gear, refractory lining, catch-wheel device, kiln head sealing device, kiln tail sealing device, kiln hood, and other components. On the cylinder, there is a large gear ring fixed with a spring plate near the kiln tail, some pinions below are engaged with it, jointly forming the drive gear. In normal operation, the main drive motor will transfer power to this gear device through reducer to run rotary kiln. The raw material usually enters the rotary kiln from the upper end and move slowly to another end along with the chamber as it rotates. In this process, raw materials will be heated by high temperature and then decompose and produce chemical reactions so that their state finally changed. Under normal conditions, the heat source of indirect fired rotary kilns is supplied from the kiln burner outside the kiln. This kind of way protects the integrity of raw materials, while the heat source of the direct-fired rotary kiln is inside the kiln. Besides, the rotation speed and temperature of the cylinder are tightly controlled and changed according to different desire processes and material applications. After the calcination is completed, the clinker will be pre-cooled in the chamber and then be sent into the cooler for further cooling.

Rotary kiln is a rotating kiln that does the mechanical, physical, or chemical treatment of solid materials. Rotary kiln is widely applied to materials building, metallurgy, chemical industry, environmental protection, and many other industries.
By feeding manner: according to whether the material into the kiln with water, rotary kiln can be divided into a dry rotary kiln and wet rotary kiln. The wet kiln can be divided into the inflow method and the injection method. In addition to the dry kiln, there is also a ball made of raw material into the kiln after heating, forging, and burning, known as the semi-dry process.
By length-diameter ratio: Generally, the L/D of the dry kiln is equal to 16 will be called as a short kiln, while L/D of the wet kiln is equal to 30-42 will be called as a long kiln. Spraying kiln has a short drying process, UD is equal to 20-25.
By heating method: there are internal heating kilns and external heating kilns, and external heating kilns are used for indirect heating to treat materials with highly toxic substances or materials requiring a high concentration of flue gas and high purity.
The invention of the rotary kiln not only made the cement industry develops rapidly but also promoted peoples research on the application of rotary kiln. Soon rotary kiln was widely used in many industrial fields, and became more and more important in these industries, and became the core equipment of corresponding enterprises. In the application field of rotary kiln, the cement industry takes a big share.
As for the principle of the rotary kiln, the fuel from the kiln head injection, combustion in furnace to produce heat, and heating raw meal, thus calcining raw meal into clinker, and the hot air generated by material exchange enter into the kiln system from the feeding end, at the end, it will be discharged into the atmosphere from the chimney, but for different kilns, the application and process also can be different.
A complete process of rotary kiln manufacture can be usually divided into the following five steps: rotary kiln design, transportation, operator requirement, installation, debugging. There are some detailed sections in the installation of rotary kiln be omitted here, feel free to ask!
The competition between rotary kiln manufacturers will directly affect the rotary kiln price, generally, if a manufacturer is located in a highly competitive region, the rotary kiln price will naturally decrease. On the contrary, when the competition is not fierce, some manufacturers will take this opportunity to raise the price of rotary kiln.
There are many models of the rotary kiln on the market, different models have different parameters such as calcination effect, processing capacity, and output, etc. Under normal circumstances, the cost of a large-size rotary kiln must be relatively high, so the price of a large-size rotary kiln is much higher than that of a small-sized one.
The demand for rotary kiln directly affects the rotary kiln price. When the rotary kiln is hot in the market, there will be in short supply and the rotary kiln price will naturally be very high. On the contrary, if there are few users who need to buy the equipment and the quantity of the manufacturer is large, the rotary kiln price will be very low at this time.
If a manufacturer owns large scale, strong strength, relatively speaking, the process is more sophisticated, the cost of production is low, the rotary kiln price will be much lower; On the contrary, the backward production process of the manufacturers and serious waste of resources in production will result in high rotary kiln price.

Imagine a rotary kiln for cement designed to completely eliminate the risk of shell constriction and the need for tyre migration monitoring systems.Thats the ROTAX-2, which suspends the kiln shell inside tangentially suspended tyres on self-adjusting rollers. That means theres no wear between tyre and kiln, and no need for lubrication.Instead, the drive is connected directly to the supporting rollers, and the kiln rotation is driven by friction between the rotating support rollers and the kiln tyre
The innovative suspension design of the ROTAX-2 means it can offer optimal mechanical reliability compared with traditional rotary kilns. And when its time to inspect or maintain the kiln, there are no hidden parts. Everything is visible, for easy inspection and maintenance.
The ROTAX-2 is kept in position by an automatic hydraulic thrust device (HTD) that controls the axial motion of the kiln.Our HTD can take up the full axial load of the kiln, meaning that roller skewing is not required to take up axial forces.
A rotary kiln for cement is only as efficient as the seals on its inlet and outlet zones. After all, if false air enters the kiln system, fuel consumption goes up, production output goes down, and operating expenses skyrocket.
ROTAX-2 Rotary Kiln installations feature direct electro-mechanical drive-through rollers, as well as a fully self-aligning roller support system. The roller suspension maintains constant contact with the supporting rollers. This ensures the efficient transmission of torque and cuts down on the stress that causes pitting and cracks.
Kiln rotation is driven by friction between the rotating support rollers and the kiln tyre. At the same time, a redesigned tyre attachment system allows the kiln shell to expand radially, which means theres no need for lubrication between the tyre and kiln.
Because theres no kiln girth gear and only two supports, maintenance costs are low. And kiln axis alignment is not affected by settling of the foundation, so periodical kiln axis realignment is unnecessary.
Graphite seals at the inlet and the outlet of the kiln reduce false air intake, but theyre flexible enough to follow the kilns movements. These seals require no greasing and are practically maintenance-free.

Product Name: Large Cement Production Plant / Cement Factory for Sale Capacity: 5000-10000 TPD Equipment: raw material crusher, raw meal grinding machine, storage yard, stacker reclaimer, preheater cyclones, rotary kiln, grate cooler, cement mill, etc. Cement Production: ordinary portland cement, pozzolana portland cement, white portland cement, quick-setting cement, refractory cement, etc.
In contrast to the mini cement plants, we usually call the cement plant with a clinker production capacity of more than 5000 TPD as the large cement plant. As a manufacturer who specializes in cement technology development and equipment upgrading and has over decades of cement machinery manufacturing experience, AGICO has the ability to design and build large cement plants with clinker production of up to 10,000 tons per day.
With the increase of plant scale and production capacity, the size and capacity of the crushers, cement mills, rotary kilns, and other machines in the cement plant also increase correspondingly. Therefore, the increase of plant scale should be accompanied by the growth and development of cement manufacturing machinery so as to maintain or even improve the efficiency and productivity of cement plants.
Compared with mini cement production lines, large cement plants have higher energy consumption. But take into account their output, they actually have a higher energy utilization rate and production efficiency, which can save production costs for cement manufacturers in the long run. Also, the operating efficiencies of large plants are high. The fuel consumption is around 650 700 kcal/kg clinker; power consumption is between 65-80 kWh/ton, and man-hours required per ton of cement are as low as 0.15.
AGICO large cement plants are best suited for manufacturing cement by dry process. The cement-making machines in our large cement plants include cement crushers, cyclone preheating systems, rotary kilns, cement mills, and other auxiliary equipment.
The purpose of raw material preparation in the dry process of cement manufacturing is to reduce large-sized raw materials to the proper size and mix them into homogenized raw meals. We will install the most suitable crushing machinery in the cement plant according to the raw materials and production requirements of customers, so as to achieve economic and green production as much as possible.
The application of cyclone preheating system in cement plant hugely reduces the heat loss and fuel consumption in the clinker burning process, and also significantly reduces the floor area and pollution emission of the whole plant.
The 5-stage cyclone preheater is the most installed preheating system in our large cement plants. According to customers requirements, we could design other stage preheaters for the cement plant. The cyclone preheater uses hot exhaust gas from the rotary kiln as its heat source. Before entering the rotary kiln, the cement raw meal heat exchanges with the high-temperature gas in the preheater to preheat.
The rotary kiln is where the burning phase of the cement manufacturing process takes place; it is the core part of a cement plant. The raw meal in the rotary kiln will be heated to 1,500 during the burning process to form cement clinker.
The production capacity of a cement plant is directly determined by the capacity of the rotary kiln. Our large rotary kilns can fully meet the requirement of bulk cement production. Together with the advanced preheating system, our rotary kilns could achieve high rotary speed and high output per unit volume. The good sealing effect of our rotary kilns allows them to fully recycle the waste heat and produce high-quality clinker.
Cement mills are used for raw material reduction and cement grinding in the cement manufacturing process. The cement grinding process is the final manufacturing stage at a cement plant. After this process, the clinker will become fine cement powders and ready to be packed.
The most used cement mills in our large cement plants are cement ball mills and vertical roller mills. Both of them can well undertake the task of cement grinding, we will take their production efficiencies, power consumptions, investment costs, product particle shapes and sizes, maintenance fees, and other elements into account and decide which one to use when designing a cement plant.
