Active Lime Rotary Kiln for Lime Production Line , 30kw Kiln Equipment
Application of Lime Rotary Kiln
Rotary kiln is thermal equipment to heat materials. It is widely used in the fields of cement, nonferrous metallurgy, ferrous metallurgy, refractory material, chemical, and making-paper.
Main 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 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 device: 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.
6. Kiln head hood: including stationary type and flexible type.
Working Principle of of Lime Rotary Kiln
The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The raw material to be processed is fed into the upper end of the cylinder. While the kiln rotates, material gradually goes down towards the lower bottom, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or “firing pipe”) which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal.
