Rotary kiln is widely used for many industries like metallurgy, chemical industry, building refractory materials, environmental protection, etc. The Rotary Kiln consists of cylindrical shell, supporting device, supporting device of thrust roller, driving unit, moveable kiln head, sealing device on the tail of kiln, coal dust pipe device, etc. the kiln body has a certain tilt angle with level. The whole kiln body is supported by the roller supporting device, and it is also equipped with thrust roller device to control the up and down movement of the kiln body. Product 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 variable motor, 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, 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.
