Active rotary lime kiln

Introduction of Product:

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.

Product Introduction:

 

Active rotary lime kiln belongs to building material equipment, according to different materials, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln. Cement kiln is used for making cement clinker and there are dry and wet methods to make cement clinker. Metallurgy chemical kiln is widely used for magnetic roasting of poor iron ore and oxidizing roasting of chrome and nickel in the steel factory; backing high-alumina mine in the refractory material factory; baking chamotte and alumina in the aluminum factory and baking chrome ore and chrome powder in the chemical plant. The Lime Kiln is used for roasting active lime in steel works and ferroalloy plants and light roasting dolomite.

 

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.
