Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and fuel device.

As a heated pivoting part, cylinder is made of highquality carbon steel plate and supported on the support device by wheel belt. There is mechanical or hydraulic pressure catch wheel on the first or several support device in order to control the turning of cylinder. Gears make cylinder rotate according to process required rotating speed through the ring gear in the middle of cylinder. Because of the need of installation or maintenance, the bigger rotary kiln has auxiliary rotary gears, which makes cylinder gyrate more slowly. To prevent enter of cold air and dust overflow, the reliable kiln tail and head sealing equipment are installed on feed and discharge end.

Rotary kiln Product application:

Rotary kiln is a kind of thermal equipment, heating materials. It is widely applied in the fields of cement building materials, nonferrous metallurgy, ferrous metallurgy, refractory material,

chemical materials and paper making.

Rotary kilnProduct feature:
1. Support device: advanced shaft structure, automatic temperature measuring device and electrical heating device.
2. Catch wheel: including mechanical wheel and hydraulic pressure catch wheel.
3. Gears: single or double. The rotating speed is controlled by regulating motor, DC motor or variable frequency and speed regulation motor. Be reliable, energysaving and efficient.
4. Cylinder tyre bolster: lower bolster has three types: fixed, zoom and floating. Its structure is simple, replacement is convenient and it won’t hurt cylinder when it needs a change.
5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, graphite block sealing and combination for above. The feature is adaptive for cylinder rotating and swing. And sealing effect is very good.
6. Kiln head hood: including stationary type and flexible type.

Rotary kiln 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.

Our high-performance dual wavelength sensors offer unequalled performance for accurate and repeatable measurements on kiln applications. These sensors can operate properly when the target energy signal is diluted

over 99% by such things as dust and smoke. To effectively measure targets through flames, the 1400 and 4400 Series are recommended. These singlewavelength sensors utilize a very narrow band 3.8 micron filter that provides unequalled performance with measurements through flames.

Rotary kiln Working principle:

The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder.

As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (cocurrent), but usually in the opposite direction (countercurrent). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burnerpipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal.
