Lime Rotary Kiln

  • Introduction of Lime Rotary Kiln

    Lime Rotary Kiln is composed of cylinder, gears,support decvice, kiln liner and kiln tail sealing equiment, kiln head hood and combustion.Lime kiln as a heating device is a high-quality steel processed, is supported on the support device by tyre, and there is manchanical 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 lime 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 is installed on feed and discharge end. 

     

    Features of Lime 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, machine and frequency variable motor. Be reliable energy-saving, and efficient.

    4.Cylinder type: 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.

     

    Working Principle of Lime Rotary Kiln

    Materials enter from the kiln outlet (the high end of the cylinder) into the kiln for calcination. Due to the tilt cylinder and slowly rotating, materials are not only rolling along the circumferential direction but also moving along the axial direction (from high to low), continuing to complete the process. Finally, the clinker enter into the cooler through kiln hood for cooling. Fuel is sprayed into the kiln through the kiln head, and exhaust gas produced by combustion exchanges with material, and then discharges from kiln outlet.
