History of Rotary Kiln
The rotary kiln, originally designed as a British cement kiln in 1877, was born in England, grew up in the United States and was completed in France in the 1900s and has been developed and used in various fields such as ore extraction, metal smelting and waste disposal
How does Rotary Kiln work?
A large cylinder is laid horizontally at a slightly inclined angle, and the raw material is fed from the upper side while rotating the cylinder. The raw material is rotated by gravity along a slight slope, moving downward, outward from below, and heated from inside or outside the cylinder during moving.
The most important technology in the rotary kiln is how to perform the heating temperature, the residence time, the tilting angle, etc. according to the material properties. In particular, maximizing heat transfer between material and heat source to increase thermal efficiency requires skilled design engineers and skilled construction. Rotary Kiln is one of the most important items with long experience and technology.
