INTRODUCTION
Lime rotary kiln is used to produce quicklime through the calcination of limestone (calcium carbonate). Lime rotary kiln is specialized design for production of active lime.
ZK lime rotary kiln can work with vertical preheater and vertical cooler to achieve the advantages like high use ratio of raw materials, complete calcination, even quality, good quality lime, high capacity output, environmental and energy saving, simple operation and longer working life. This kiln is very suitable for limestone calcination for industries like metallurgy, chemical, construction materials and etc.
PROCESS
1. Support device: advanced shaft structure, automatic temperature measuring device and electrical heating.
2. Catch wheel: including two kinds of 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, 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.
