Active lime rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, hood of kiln head and alkene material device etc.. Active Lime rotary kiln as a heating device is a high-quality steel processed, is supported on the support device by tyer, and there is hydraulic pressure catch wheel on the first or some gear in order to control the turning of cylinder. Gearing gyrate according to process-required rotating speed by ring gear in the middle of cylinder.
Because of the need of installation or maintenance, the bigger Active lime 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 hed sealing equipment are installed on feed and discharge end. The most common are Cement clinker Rotary kiln, etc., more models to choose.
Feature of active lime rotary kiln:
1. Cylinder tyer bolster: lower bolster has three types: fixed, zoom and floating. The structure has simple replacement that is convenient and won' t hurt cylinder.
2. Gears: single or double. Control the rotating speed by blucher, DE machine and frequency variable motor. Reliable energy-saving, and efficient.
3. Sealing equipment: there are many kinds for choice according to kiln models .
4. 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.
5. Support device: advanced shaft structure, automatic temperature measuring device and electrical heating.
