Cement Rotary Kiln

Cement kilns are used by the cement industry in the production of cement. Portland cement, used in almost all construction applications, is the industry's primary product. Essentially all of the NO2, emissions associated with cement manufacturing arse generated in the kilns because of high process temperatures.

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.

To make cement, raw materials such as limestone, cement rock, sand, iron ore, clay and shale are crushed, blended and fed into a kiln. These materials are then heated in the kiln to temperatures above 2900°F to initiate a chemical reaction (called "fusion") that produces cement "clinker," a round, marble-sized, glass-hard material. The clinker is then cooled, mixed with gypsum and ground to produce cement.

Nearly all cement clinker is produced in large rotary kiln systems. The rotary kiln is a refractory bricklined cylindrical steel shell equipped with an electrical drive to turn it at 1-3 rpm, through which hot combustion gases flow countercurrently to the feed materials. The kiln can be fired with coal, oil, natural gas, waste or a combination of these fuels. Currently, most cement plants (over 75 percent) are coal-fired.

There are four types of kilns in use - long wet kilns, long dry kilns, kilns with a preheater and kilns with a precalciner. The long wet and dry kilns and most preheater kilns have only one fuel combustion zone, whereas the newer precalciner kilns and preheater kilns with a riser duct have two fuel combustion zones.

In a wet kiln, the ground raw materials are suspended in water to form a slurry. In a dry kiln, the raw materials are dried to a powder. Newer cement plants normally use the dry process because of its lower energy requirement.

Because the typical operating temperatures of these kilns differ, the NO2 formation mechanisms also differ among these kiln types. In a primary combustion zone at the hot end of a kiln, the high temperatures lead to predominantly thermal NO2, formation. In the secondary combustion zone, however, lower gas-phase temperatures suppress thermal NO2 formation. Energy efficiency is also important in reducing NO2 emissions; for example, a high thermal efficiency means less heat and fuel are consumed and, therefore, less NO2 is produced.

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%.

Vipeak brand rotary kiln (titanium pigment kiln, sintering furnace, industrial furnace, kiln, acid pellet) made by Vipeak Heavy Industry. Who used for new type complete rotary kiln equipments. Vipeak 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.
