Rotary Kiln, also known as Rotary Calciner, is an equipment used to process the building materials. In cement industry, Rotary Kiln can calcify cement raw materials into cement clinker; In chemical industry, Rotary Kiln is used to produce sodium bicarbonate, to calcine phosphate fertilizer and barium carbonate and other carbonic acid products etc; In metallurgy industry, Rotary Kiln is used in the production of aluminum hydroxide etc. Rotary Kiln is of good calcination and of high product quality.

Principle of Working:
Rotary Kiln has a drum-shaped structure with a slope of 3-3.5%. It is the rotation of the drum makes the materials mixed  with each other and touch each other to facilitate reaction. Pulverized coal combustion at Kiln head produces a large amount of heat which passes on to materials in ways of heat radiation, heat convection, brick kiln (kiln skin) transmission way etc. Materials relying on  angle of kiln cylinder and the rotation of the kiln stove move forward.

Characters:
(1) Different sealing devices are designed according to different types of kiln to ensure good seal performance.
(2) Strong adaptability, simple structure, less wear, sound dust prevention and heat protection.
(3) Evenly heated, high thermal efficiency, continuous production, good quality of burning.
(4) Small venue, high mechanization degree.
