Rotary Kilns are commonly used for heat processing of minerals and aggregates such as lime, cement, and iron ore . To achieve consistent quality results, it is important to maintain a uniform product temperature at the kiln entry, mid zone, and discharge. In most rotary kilns, the challenge with temperature process control is that the temperature sensor must view through flames or heavy smoke and dust. Consequently, when selecting a sensor, the design, wavelength, and alignment are all important considerations.
Rotary Kiln Advantages and applications:
A rotary kiln is ideal for calcining high-grade cement in cement plants. It is also commonly used in the production process of catalytic agent, molecular sieve and zinc oxide, etc. As a result, you can find a rotary kiln in variety of industries, like steel annealing and nonferrous smelting industries, metallurgy and chemistry fields, and building industries, and more.
A rotary kiln, which is also called a rotary calcine kiln, is a commonly used building material machine. Classifying by material properties, a rotary kiln falls into cement kilns, metallurgy chemical kilns, and lime kilns.
We at Esong can provide kilns with different shapes, including mesh-belt kiln, rotary furnace, tunnel furnace, shuttle kiln, push board kiln, etc.
All our rotary kiln features simple structure, reliable and convenient control of production process, few wear parts and high operation rate.
If you are looking for rotary kilns with solid structure and stable operation, don’t hesitate to contact us.
Introduction of different types of rotary kilns:
1. A cement rotary kiln is primarily used for calcining cement clinker. It can be divided into dry process rotary kilns and wet process rotary kilns.
2. A metallurgy chemical kiln is mainly used for magnetized roasting of lean iron ore, and oxidizing roasting of chrome ore and nickel ore, etc. in steel plants.
In refractory plants, this rotary kiln is mainly used for roasting different high-alumina refractories.
In aluminium factories, it is mainly used for roasting clinker and aluminum hydroxide.
When used in chemical industry, it is mainly used for roasting chrome ores, and chrome powders, and more.
3. Lime kiln is applied to roast active lime and dolomite which are commonly used in steel factories and ferroalloy factories.
Rotary Kiln Features:
1. Through technological innovation, our rotary kiln is designed with international leading wheel catch device, high precision plunger metering pump, high accuracy speed control valve and contact graphite block sealing device, etc.
2. In order to improve machinery automation, an industrial computer is used for showing the calcining condition, and a fluorescent screen is adopted for showing the simulated process flows. An infrared scanner is utilized for transmitting the calcining condition to the computer.
These new technologies provide our rotary kiln with strong visual sense, convenient operation and reliable performance. They help stabilize thermal regulation and improve operation efficiency.
4. Comparing with other similar cement production equipment , the operation rate of our rotary kiln increased by 10%, production increased by 5%-10% and heat consumption decreased by 15%.
Rotary kiln technologies
This portion of our web site is dedicated to give users or potential users of rotary kilns general information. This information can be helpful for learning general terminology, maintenance, or progresses in the technology. It will not talk about specific uses or processes, but we hope it answers frequently asked questions about rotary kilns.
Rotary kilns are used to heat solids to the point where a required chemical reaction(s) takes place. The rotary kiln is basically a rotating inclined cylinder. Solids retention time in the kiln is an important design factor and is set by proper selection of the diameter, length, speed, slope and internals design. There are two basic types of rotary kilns; direct fired and indirect fired.
NFLG designs and supplies both direct fired and indirect fired rotary kilns for a wide variety of applications. We have supplied over a thousand rotary kilns ranging in size up to 7.6 meters in diameter and 190 meters in length.
NFLG brand rotary kiln (titanium pigment kiln, sintering furnace, industrial furnace, kiln, acid pellet) made by Shanghai Shibang mining Machinery Co., Ltd. Who used for new type complete rotary kiln equipments. NFLG brand rotary kiln is the main equipment for calcining cement clinker and it can be used widely for cement industry, metallurgy industry, chemical industry, etc. The rotary kiln is composed of the shell, the supporting device, the supporting device with thrust roller, the driving device, the movable kiln head, the sealing device at kiln tail, the combustion device, etc. It has the simple structure and reliable operation, at the same the production process of the rotary kiln can be controlled easily.
Through the technical renovations, the rotary kiln calcining system equipment made has adopted the advanced hydraulic thrust roller device, the high measuring precession plunger pump, the variable speed adjusted valve, the contact graphite block sealing device and the other national advanced technologies. In order to raise up automation degree, the industrial TV has been used at the kiln head for monitoring of kiln, the simulation phosphor screen has been used for display of process flow; the infrared scanning system has been adopted for calcining zone to directly reflect the burning conditions on the computer. With the use of these new of these new technologies, it is direct in vision, convenient in operation and reliable in use. Therefore, the thermal condition can be stabilized and the running rate of equipment can be raised. Compared to same sized equipment, its running rate has been raised 10% up, production has been increased 5-10% and heat consumption has been reduced 15% down.
Rotary kiln belongs to building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.
Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory; baking high-alumina mine in the refractory material factory; baking chamotte and alumina in the aluminum factory and baking chrome ore and chrome powder in the chemical plant. Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.
