Rotaryrotary

kilnkiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different processing materials. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different processing materials. The cement kiln is mainly used for calcining cement clinker, and it is divided into two types: cement kiln and wet kiln. Metallurgical chemical kiln is mainly used for magnetization roasting of iron ore in iron and steel industry in metallurgical industry; oxidizing roasting of chromium and ilmenite; roasting of high alumina bauxite ore and roasting clinker of aluminum plant in refractory plant; aluminum hydroxide in chemical plant; And minerals such as chrome ore. The lime kiln (ie active lime kiln) is used to roast the active lime and light burnt dolomite used in steel plants and ferroalloy plants.

Basic information of rotary kiln

In many production industries such as building materials, metallurgy, chemical industry and environmental protection, the rotary material is widely used for mechanical, physical or chemical treatment of solid materials. Such equipment is called rotary kiln.  

    

back to the brick

The application of the rotary kilnkiln originated from cement production. In 1824, the British cement worker J Asp invented the intermittent operation of the kiln; in 1883, the German Dietz invented the continuous operation of the multi-layer vertical kiln; 1885 British Lan Eransome invented the rotary kiln, which was put into production after patents were obtained in the UK and the US, and quickly gained considerable economic benefits. The invention of rotary kiln has made the cement industry develop rapidly, and it has also promoted the research on the application of rotary kiln. Soon, rotary kiln is widely used in many industrial fields and is becoming more and more important in these productions, becoming the core of corresponding enterprise production. device. Its technical performance and operation determine the quality, output and cost of the company's products to a large extent. “As long as the big kiln turns, there are thousands of dollars.” This folk song is a vivid description of the importance of the rotary kiln in production. In the field of application of rotary kiln, the cement industry has the largest number.  

The whole production process of cement is summarized as “two grinding and one burning”, in which “one burning” is the process of burning raw materials prepared by grinding and burning into clinker under the high temperature of rotary kiln. Therefore, the rotary kiln is the main engine in the production of cement, commonly known as the "heart" of the cement factory. In the building materials industry, in addition to calcined cement clinker, rotary kiln is also used for calcining clay, limestone and slag drying. In the production of refractory materials, rotary kiln calcined raw materials are used to make the dimensional stability and strength increase. Processing and forming. In the non-ferrous and ferrous metallurgy, iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, bismuth and other metals are used as smelting equipment for rotary kiln, and ore, concentrate, intermediates, etc. are sintered and calcined. For example, aluminum is used to roast aluminum hydroxide into alumina; it is used in iron making to produce pellets for blast furnace ironmaking; foreign "SL/RN method" and "Krupp method" use it for iron ore Direct reduction; chlorination volatilization roasting method uses it to extract tin and lead. During the beneficiation process, the lean kiln is used to magnetize the lean iron ore to change the original weak magnetic properties of the ore to strong magnetic properties to facilitate magnetic separation. In the chemical industry, rotary soda is used to produce soda, calcined phosphate fertilizer, and barium sulfide. In the 1960s, LapPle et al. invented a new process for producing phosphoric acid from rotary kiln. The method has the advantages of low energy consumption, low power consumption, no use of sulfuric acid and available medium and low grade phosphate rock, and is quickly popularized.  

In the production of rotary kiln, there is often a phenomenon of ring formation. Now most of them use the method of cleaning workers, but they affect production and increase production costs. The rotary kiln cleaning machine that has just been developed avoids this phenomenon. Can handle the ring phenomenon very well.  

In addition, in terms of environmental protection, developed countries in the world have used cement kilns to burn hazardous waste and garbage for more than 20 years. This not only reduces waste and harmless waste, but also uses waste as fuel to save coal powder. Recycling of waste.  

Types of rotary kiln The

cement industry has developed different production methods and different types of rotary kiln in the development process. According to the raw material preparation method, it can be divided into dry production and wet production. The rotary kiln is compatible with the production method. Dry rotary kiln and wet rotary kiln. Due to the different kiln heat exchange devices in the kiln, they can be divided into different types of kiln.  

Classification of

rotaryCement rotary kiln  

kilncement kiln currently has two major categories, one is the kiln cylinder lying (slightly inclined), and can be used for rotary motion called rotary kiln (also called rotary kiln); The kiln cylinder is called a vertical kiln.  

1. Types of wet rotary kiln:  

The cement kiln used in wet production is called wet kiln, and the wet production is to make the raw material into slurry containing 32%~40% water. Since it is prepared into a fluid slurry, the raw materials are well mixed, the raw material components are uniform, and the quality of the fired clinker is high, which is a main advantage of wet production.  

2, the type of:  

dry rotary kilndry rotary kiln and wet rotary kiln compared to the advantages and disadvantages of the opposite. The dry process produces the raw meal as a dry raw meal with a moisture content generally less than 1%, so it reduces the amount of heat required to evaporate moisture than the wet process. Because of the high temperature of the exhaust gas, the hollow kiln has a low heat consumption. The dry process produces the raw meal into a dry powder, which is less fluid than the mud. Therefore, the raw materials are not well mixed and the ingredients are not uniform.  

The cement rotary kiln is  

mainly used for calcining cement clinker, and is divided into two categories: cement rotary kiln and wet process cement rotary kiln. Metallurgical chemical rotary kiln is mainly used for magnetization roasting of iron ore in iron and steel industry in metallurgical industry; oxidizing roasting of chromium and ilmenite; roasting of high alumina bauxite ore and roasting clinker of aluminum plant in refractory plant; aluminum hydroxide in chemical plant Minerals such as ore and chrome ore. Lime rotary kiln (ie active lime rotary kiln) is used for roasting active lime and light burnt dolomite for steel and iron alloy plants.  

The wet rotary kiln process is

only introduced and analyzed by the wet rotary kiln process. The wet rotary kiln body is usually long (length to diameter ratio is 30 to 40). In order to increase the heat transfer area of ​​the kiln, a chain is often attached at the end of the kiln to accelerate water evaporation. When the wet rotary kiln is produced, water is added to the raw mill to make the raw material into water.  

    

rotary kiln

30% to 40% of the slurry in theis homogenized to the required slurry. The slurry is sent to the kiln for calcination of the mature material. The kiln clinker is cooled by the cooler and sent to the clinker. Drying and grinding into pulverized coal and then burning to supply the calories required for calcination.  

The characteristics of the calcination of the wet rotary kiln are: because the raw material is made into mud, the adaptability to the heterogeneous raw material is strong, the raw material composition is uniform, the process is stable, the clinker quality is high, the clinker strength grade is high, and the grinding is high. There is less dust in the process and less fly ash at the kiln. However, in the wet production process, 30% to 40% of the slurry moisture is evaporated, which requires a large amount of heat, and the energy consumption accounts for 1/2 to 1/3 of the cement cost, which is higher than that of the vertical kiln and the dry rotary kiln. Due to high heat consumption, high energy consumption, and large water consumption during production and consumption of water resources, wet production has been classified as a restricted kiln type in China.  

The type of cement shaft kiln is characterized  

by two types of shaft kiln currently used in China: ordinary shaft kiln and mechanical shaft kiln.  

Ordinary shaft kiln is manual feeding and manual unloading or mechanical feeding, manual unloading; mechanical shaft kiln is mechanical feeding and mechanical unloading. The mechanical shaft kiln is continuously operated, and its production, quality and labor productivity are higher than ordinary shaft kiln. According to the requirements of building materials technology policy, small cement plants use mechanized vertical kiln to gradually replace ordinary shaft kiln.  

The main structurekiln body includes

of the rotary1. kiln shell, which is the main body of the rotary kiln (rotary kiln). The kiln shell steel plate has a thickness of about 40mm, near the tire ring, because the bearing capacity is relatively large, the kiln shell here The steel plate should be thicker. The interior of the kiln shell is covered with a layer of refractory bricks of about 200 mm. When the kiln shell is in operation, due to the relationship between high temperature and load bearing, the kiln shell will have an elliptical deformation, which will exert pressure on the kiln brick and affect the life of the kiln brick. At the end of the kiln, about one meter long is tapered, so that the material from the preheater feed chamber can enter the kiln more smoothly.  

2. The tire ring, support roller, bearing, tire ring and support roller are used to support the weight of the kiln. The tire ring is sleeved on the kiln shell, and it is not fixed between the kiln shell. The kiln shell and the tire ring are separated by an iron plate to keep a certain gap between the tire ring and the kiln shell. too small. If the gap is too small, the expansion of the kiln shell is limited by the tire ring, and the kiln brick is easily damaged. If the gap is too large, the relative movement between the kiln shell and the tire ring, the friction is more harmful, and the elliptical deformation of the kiln shell is more serious. It is usually necessary to add lubricant between the two. Our door can estimate the degree of elliptical deformation of the kiln shell by the relative motion between the kiln shell and the tire ring.  

There is a difference in thermal conductivity between the kiln shell and the tire ring. It is necessary to use an external windmill to help the kiln shell to dissipate heat and balance the temperature difference between the two. Otherwise the expansion of the kiln shell will be limited by the tire ring. When the kiln is opened, the heating rate of the kiln shell is higher than that of the tire ring. The kiln must control the heating rate of the rotary kiln (rotary kiln) at 50 °C / h, which is beneficial to protect the kiln brick. Usually, the roller is 50-100 mm larger than the wheel. The roller bearing is made of babbitt. If the bearing loses lubrication, the bearing will burn out due to excessive temperature. There is cooling water at the bearing for circulating cooling. In order to reduce the heat radiation of the kiln shell to the tire ring, the temperature of the roller is too high, and a heat insulation plate is added between the two to reduce heat radiation. Rotary kiln (rotary kiln) generally has 2 to 3 sets of rollers.  

3. The thrust roller  

thrust roller is the limit switch that limits the rotary kiln (rotary kiln) when it is eaten or eaten. Because the support roller is wider than the kiln tire, in order to make the roller and the belt move up and down, the wear is even. A thrust roller is provided on the end surface of the tire ring.  

The thrust roller only acts as a barrier, and the roller itself has no power. The eating and eating of the kiln body depends on the deviation of the roller. The supporting wheel and the center line of the kiln have a certain angle, so that the supporting wheel gives the kiln body an upward force and moves the kiln shell upward. Sometimes the raw material powder is sprinkled or the roller is wiped clean, and the friction coefficient is increased to move the kiln up. When the kiln body is eaten, as long as the graphite powder is sprinkled between the supporting wheel and the wheel belt, the friction between the two can be reduced. When the rotary kiln (rotary kiln) eats and touches the Y1 switch, the hydraulic system starts to take action, the hydraulic system eats for 1 minute, stops for 4 minutes, and then repeats the action of stopping for 1 minute for 4 minutes until the kiln tire ring touches. Go to the Y5 position. At this point, the kiln body began to eat, the hydraulic system was released for 2 minutes, stopped for 4 minutes, and then repeated. Until the kiln touches the Y1 position and eats again. Repeat the above process continuously. When the hydraulic system stops, the internal pressure does not change.  

The hydraulic system also has three to limit switches. When eating, if the Y1 switch is faulty, the kiln body will touch the Y second switch, the system will alarm (the kiln body has exceeded the eating range of 30mm), and if it touches the third switch, the system will Jumping (at this point, beyond the 50mm range). When the rotary kiln (rotary kiln) is eaten, if the first switch is faulty, the rotary kiln (rotary kiln) will alarm when it touches the second switch, but it will not jump because there is a thrust roller. Limiting the kiln shell to eat the limit
