Best Rotary Calcination Kiln for Activated Carbon
1.Introduction of Rotary kiln:
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 tyre, and there is machanical or 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 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.
2.Features of rotary kiln:
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
