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.

FEECO is a leading manufacturer of highly engineered, custom rotary kilns for processing solids. Our high temperature kilns have earned a reputation for their durability, efficiency, and longevity. We offer both direct- and indirect-fired units.

Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum.

Direct-fired kilns utilize direct contact between the material and process gas to efficiently process the material. Combustion can occur in a combustion chamber to avoid direct flame radiation, or the flame can be directed down the length of the kiln.

All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment.

Indirect-fired kilns are used for various processing applications, such as when processing must occur in an inert environment, when working with finely divided solids, or when the processing environment must be tightly controlled.

Calcination refers to the process of heating a material to a temperature that will cause chemical dissociation (chemical separation). This process is used frequently in the creation of inorganic materials, for example, the dissociation of calcium carbonate to create calcium oxide and carbon dioxide.

Thermal desorption is also a separation process. This process uses heat to drive off a volatile component, such as a pesticide, from an inorganic mineral, such as sand. The component is vaporized at the increased temperature, causing a separation without combustion. In some cases, an indirect rotary kiln would be best for this application, because the volatile chemicals may be combustible. The indirect kiln will supply the heat for desorption, without the material coming into direct contact with the flame.

Organic combustion refers to the treatment of organic wastes with the intent of reducing mass and volume. Organic waste is treated in the kiln, leaving behind an ash with considerably less mass and volume. This allows for more efficient and effective deposit of waste materials into landfills.

Sintering is the process of heating a raw material to the point just before melting. This increases the strength of the material, and is commonly used in the proppant industry, where sand or ceramic materials are made stronger.

Heat setting involves bonding a heat resistant core mineral with another, less heat resistant coating material. Unlike an unheated coating process, here, a rotary kiln heats the coating material to just below liquefaction point, allowing it to coat the heat resistant core more evenly and more securely. This process is commonly seen in the manufacture of roofing granules, where a mineral such as granite is coated with a colored pigment, producing a product that is both durable and aesthetically pleasing.

Reduction roasting is the removal of oxygen from a component of an ore usually by using carbon monoxide (CO). The CO is typically supplied by mixing a carbonaceous material such as coal or coke with the ore or by feeding it separately. Examples are the reduction roasting of a hematite containing material to produce magnetite that can be magnetically separated. In the Waelz process, zinc oxide in steel mill wastes is reduced to metallic zinc and volatilized for recovery in the off-gas system.

Daswell limestone rotary kiln are customized designed and manufactured to meet customers needs. For different production capacity needs, Daswell lime rotary kiln can come in different diameters. Daswell rotary kilns for lime calcination are of robust designs with quality materials so that they can work for long term with great performance. Besides, to ensure the high cost-efficiency of lime calcination plant, Daswell also offers vertical pre-heater and vertical coolers to work with the lime rotary kiln.

Limestone contains mainly of calcium carbonate. And when limestone is strongly heated in rotary kiln, calcium carbonate undergoes thermal decomposition to form calcium oxide, which is quicklime, and carbon dioxide (CO). This reaction takes place at 900, but the temperature in rotary lime kiln is often around 1000 degrees to make the process happen quickly. But excessive temperature is avoided because it produces unreactive, dead-burnedlime. Rotary lime kiln rotates continuously on riding rings for a period of time so that the limestone can be burnt down thoroughly. During the operation of rotary lime kiln, quicklime will be left inside, with carbon dioxide being driven off.

Rotary kiln for lime production is a central equipment for quicklime plant. In fact, it has long been used for making quicklime. And the design of limestone rotary lime has been constantly designed and innovated with the improvement of high technology as well as the great materials. Daswell modern rotary lime kilns are made of high quality materials with high technology. It is a rotating cylindrical vessel. And it is slightly inclined to horizontal, with the higher end being the material inlet and lower end to discharge quicklime. As a result, the processed limestone in the rotary lime kiln will move to lower end to be discharged. Its shell is often made of rolled mild steel plates which are welded to form a cylinder. And the lengths and diameters of the cylinder vary from each other depending on the needs of customers. Daswell provides limestone lime kiln with length ranging 40-72m, while the diameter ranging 2.5-5.24m. Daswell rotary lime kilns tend to shorter because they can work with vertical preheater and vertical cooler.

Except for the rotary lime kiln vessel itself, there are other parts which can be important for the limestone lime kiln. For example, the refractory lining inside the kiln shell, riding rings, rollers, and furnace and so on. As for the refractory lining, it is used to insulate the lime kiln shell from the high temperature in the rotary lime kiln, and also protects the shell from the corrosive property of the processed material. For the riding rings, they are made of quality steel casting and are uniquely designed to fit the shell snugly and allow the smooth movement of the rotary lime kiln. And the rollers are used to support the limestone rotary kiln and allow the smooth rotating of the lime rotary kiln. The furnace is at and the lower end of lime rotary kiln. Through the furnace, fuel, such as oil and gas, will burn the limestone in kiln with high temperature.

How does a rotary lime kiln work? Daswell rotary lime kiln often works with vertical preheater and vertical cooler. So the lime rotary kiln process will include the process of preheater and cooler. Firstly, quarried limestone will be further crushed, sifted and washed to be proper feed material with required sizes. Then the limestone will be transferred to vertical preheater through bucket elevator. In the preheater, the limestone will be preheated by the exhaust hot air from the rotary lime kiln. For the limestone in the rotary lime kiln moves in counter current with the air flow in the kiln. And the preheated limestone will go into the rotary lime kiln for calcination. The rotary lime kiln will rotate constantly for a period of time to burn through the limestone. At the end, the burnt lime will be discharged into the cooler to cool down. Finally, the quicklime then will be stored in product silo. Please fill the form below to get free quotes. We will reply in 24 hours.

daswell lime kiln manufacturer - rotary lime kiln and vertical lime kiln

daswell lime kiln manufacturer - rotary lime kiln and vertical lime kiln

Lime kiln is also known as quicklime kiln or limestone kiln. And according to shapes and operation principles, there are rotary lime kilns and vertical lime kilns. Quicklime kiln is the core equipment of quicklime plant to burn limestone to produce quicklime or burnt lime. Lime kiln has been used for this application for long time. However, lack of high technology as well as quality materials, the traditional lime kilns often consumes lot of energy in the lime manufacturing process. With the development of high technology and quality materials, modern limestone kilns are more cost efficient than the traditional ones. As a professional lime kilns manufacturer, Daswell machinery provides high quality lime kilns, whether the rotary lime kiln or the vertical kiln, producing high capacity of uniform quicklime with low energy consumption.

Henan Daswell machinery company is a leading lime kiln manufacturer in China. We provide customized rotary lime kilns and vertical lime kilns according to your needs. With constant development and innovation, Daswell lime kilns are of robust designs with quality materials, so that they can be durable and reliable equipment for your quicklime plant. Besides, as a professional lime kiln manufacturer, Daswell always puts cost efficiency of lime production plant first and the lime kilns of Daswell are designed to be cost efficient, producing high capacity of quicklime with low energy consumption. So every part of Daswell lime kiln is carefully considered, such as the refractory lines in the lime kiln, preheater and cooler for rotary lime kiln, fuels and so on. And the sizes of lime kilns are designed according to customers needs in production capacity. In fact, except for providing high quality lime kilns, Daswell machinery offers tailored solutions for quicklime plant, including previous designing and planning in line with customers needs.

The working principles of limestone kilns are the same for rotary lime kiln and vertical lime kiln. It is well known that limestone contains mainly calcium carbonate. And when calcium carbonate is heated at proper high temperatures, usually above 1000 degrees, the decomposition of calcium carbonate will produce quicklime and carbon dioxide. And the burnt lime is the end product.

For the modern rotary lime kiln with preheater and cooler, the sifted limestone will first go to the preheater. In the preheater, the hot air from the rotary lime kiln will preheat the limestone to about 800 degrees, which as a result saves lot of energy as well as money. Then the limestone will be transferred to the rotary lime kiln. After the constant rotating of rotary lime kiln for required time, the thoroughly burnt lime will be transported to the cooler. From there, the hot quicklime will be cooled down so that they can be packed.

As for the vertical lime kiln, it contains three parts from up to down: preheating, calcining and cooling. When the limestone is feed from the top of vertical lime kiln, the limestone will go through these three parts and become burnt lime. Finally, the quicklime will be discharged from the low end of the vertical lime kiln.

The differences of rotary lime kiln and vertical lime kiln lie in that they are different in shapes and constructions. The rotary lime kiln is slightly inclined to horizontal and rotates on a set of riding rings. Traditionally, in order to burn down the limestone thoroughly, rotary lime kiln is often very long. However, modern rotary lime kiln tends to be shorter and is equipped with pre-heater and cooler to save energy as well enhance quicklime plant efficiency. For the vertical shaft lime kiln, as the name implies, is vertical. And all the processes can be done in the vertical lime kiln alone. As for capacity, rotary lime kiln can produce quicklime with larger capacity than vertical lime kiln. Daswell rotary lime kiln can produce quicklime 150-1200 ton/day, while the capacity of vertical lime kiln is 100-500 ton/day.

As stated above, Daswell provides both rotary lime kilns and vertical lime kilns. And all these lime kilns can be customized according to customers needs. So how can you choose a proper lime kiln? There are several factors to consider.
