Rotary Kiln

Rotary kiln is the main equipment for sintering cemnet clinker. The rotary kilns produced by our company can be used for chemical industry, metallurgy industry and etc. Throught technical renovations, the rotary kiln sintering system equipment made by our company has adopted high measuring precession plunger pump, variable speed adjusted valve, contact graphite block air seal and other national advanced technologies. In order to raise up automation degree, indurstrial TV has been used at the kiln head for monitoring of kiln, analog fluorescent screen has been used for display of process flow; Infrared scanning system has been adopted for sintering zone to directly reflect the burning conditions on the computer. With the use of these new technologies, it is directly in vision, convenient in operation and reliable in use. Compared to been raised 3-5% up, production has been increased 5-10% and heat consumption has been reduced 15% down.

Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and combustion. Cylinder as heated pivoting part, made of high-quality carbon steel plate, is supported on the support device by type, and there is mechanical or hydraulic pressure catch wheel on the first or some gear in order to control the turning of cylinder. Gearing gyrate is according to process-required rotating speed by ring gear in the middle of cylinder. Because of the need of installation or maintenance, the bigger clinker rotary kiln has auxiliary gears, which makes cylinder gyrate more slowly. To prevent cold air come in and dust overflow, the reliable kiln tail and head sealing equipment is installed on feed and discharge end.
Rotary kiln is a kind of thermal Equipment, it is widely used in the fields of cement, Nonferrous metallurgy, ferrous metallurgy, refractory material, chemical materials, paper making.

Features of Rotary kiln:
1. Supporting device apply rolling bearing ( few with sliding bearing) to simple the bearing structure to slow down the kiln power consumption and it also improve the maintenance and inspection conditions.

2. Catch wheel: Including two kinds mechanical wheel and hydraulic pressure

3. Gears: Single or double. Control the rotating speed by buncher, DE machine and frequency variable motor. Be reliable, energy-saving, and efficient.

4. Cylinder type bolster: Lower bolster has three types: Fixed, zoom and floating. The structure is simple, replacement is convenient and won't hurt cylinder.

5. Sealing equipment: There are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, and graphite block sealing and combination for above. The feather is adaptive for cylinder rotating and swing. And sealing effect is very good.

6. Kiln head hood: Including stationary type and flexible type.

7. Transmission device apply speed adjustable motor with big speed adjustable range, stable operation, easy to maintenance advantages. Our Rotary Kiln has slow disk kiln structure, which is composed by Diesel engine, gearbox etc. It could continue to operate when electric stops, its operation is very flexible and convenient and easy for the kiln maintenance and inspection.
