Rotary Kiln
The rotary kiln includes a long cylindrical vessel. Inside the vessel, feed material to be incinerated is subjected to high temperature for a long time to achieve the desired result.
Cements, ceramics, and limestone are materials most commonly processed by the kiln. The equipment also can be used to incinerate dolomite, produce activated carbon and reduced iron powder, and for magnetizing roasting.
Structure
The major components of a rotary kiln are the kiln body, support tyres and rollers, driven gear, and driving gear. Inside the kiln, there are refractory linings, usually refractory bricks, which insulate the kiln shell from high temperature as well as provide protection against corrosion.
Work Principle
As the kiln rotates, the refractory bricks and heat exchanger roll along with it at a low speed. The kiln is often inclined slightly from the level ground. The process material is fed into the upper end of the cylinder. During its moving downward the cylinder, the material is met by an opposite flow of hot air. There is a burner set at the lower end of the kiln cylinder, from where flame is ejected into the cylinder. The off-gas is discharged from the upper end of the cylinder. During the whole process, the material undergoes both chemical and physical changes. Finished products are discharged from the lower end.
