Rotary Kiln for Limestone Calcination in Active Lime Production Line
This series of active rotary lime kiln is the large-size advanced international calcining kiln & furnace which is developed by our company Compared with the active rotary lime kiln with the same specification made by the traditional technology, this series of active rotary lime kiln can make the production capacity increase by 30%, make the heat consumption reduce by 40% and make the discharged flue gas temperature.
The structure characteristic of active rotary lime kiln:
1. The active rotary lime kiln shell design fully take into consideration of the corner at shell flexible supporting to extend the lifetime of refractory bricks and castings.
2. Adopt supporting roller bearing with big diameter and small ratio between length and diameter to improve the reliability. The bearing is automatic self-sligning bearing.
3. The better sealing effect of new type open gear hood sealing type.
4. The spring lamination overlying type lexible sealing, double layer spring lamination sealing increase the heat insulation layer to improve the reliability and lifetime.
Working Principles of active rotary lime kiln:
The active rotary lime kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder.
As the active rotary lime kiln rotates, material grad-ually moves down towards the lower end, 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.
