Rotary kiln

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.

Structure

1. Support device: advanced shaft structure, automatic temperature measuring device and electrical heating,.

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 tyre 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 , 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

Working principle of the rotary Kiln :

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.
