Product Description

Calcination rotary kiln for bauxite 
Rotary kiln
1. Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and fuel device.
2. As a heated pivoting part, cylinder is made of high-quality carbon steel plate and supported on the support device by wheel belt.
3. There is mechanical or hydraulic pressure catch wheel on the first or several support device in order to control the turning of cylinder.
4. Gears make cylinder rotate according to process-required rotating speed through the ring gear in the middle of cylinder.
5. Because of the need of installation or maintenance, the bigger rotary kiln has auxiliary rotary gears, which makes cylinder gyrate more slowly.
6. To prevent enter of cold air and dust overflow, the reliable kiln tail and head sealing equipment are installed on feed and discharge end
 
Function and usage
 
1. Support device: Advanced shaft structure, automatic temperature measuring device and electrical heating device.
2. Catch wheel: Including mechanical wheel and hydraulic pressure
3. Gears: Single or double. The rotating speed is controlled by regulating motor, DC motor or variable frequency and speed regulation motor. Be reliable, energy-saving 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.
