Rotary Kilns are normally direct fired and lined with refractory material to protect the steel shell, reduce radiation losses and transfer heat to the material. A typical Rotary kiln is cylindrical shell, slightly inclined from the horizontal and supported on two or more tyres, which in turn rotate on rollers.
The rotary kiln heated chamber is a long horizontal tube that is rotated with one end slightly elevated. The bulk material is continuously fed into the elevated end of the tube and cascades down the length of the tube by the tube's continuous rotation.
Rotary kiln is also called a rotary calcine kiln, cement kiln, lime rotary kiln and ceramisite rotary kiln, classifying by material properties. We can provide kilns with different shapes, including mesh-belt kiln, rotary furnace, tunnel furnace, shuttle kiln, push board kiln, etc.
