This project is a calcined kaolin project with an annual output of 150,000 tons in Inner Mongolia. The Φ 4.2×76m rotary kiln provided by Henan Zhengzhou Mining Machinery Co., Ltd. , with a production capacity of ≥21t/h, is used for calcining kaolin. The rotary kiln of this project is mainly used for kaolin calcination. It has the characteristics of good calcination effect, large production capacity, high operation rate, low energy consumption, stable and reliable operation, and easy operation and maintenance. It can realize energy saving, consumption reduction, and environmental protection production.

Product advantages: 

1. There is a return spoon at the kiln tail, and there is no dead angle at the feed inlet. Both the kiln head and the kiln tail are equipped with a cold air jacket and guard plate structure, and the guard plate is made of heat-resistant steel castings, and the structural design is easy to replace;

2. The transmission part adopts frequency conversion speed regulating motor, which can adjust the speed at any time according to the specific situation, relying on the frequency conversion motor and gear drive system to provide power to rotate and stop. 

3. Energy saving and environmental protection, high efficiency, high speed regulation precision, and stable operation; Auxiliary transmission: Auxiliary transmission motor is adopted to ensure that the rotary kiln can still operate as a rotary kiln when the main power supply is interrupted, to prevent bending and deformation of the cylinder and to facilitate maintenance, and equipped with electro-hydraulic block brakes to avoid reverse rotation when the kiln is stopped; 

4. Stop wheel device: adopt hydraulic stop wheel, rely on the hydraulic station to provide pressure to push the stop wheel and kiln body, realize the up and down of the kiln, without manual intervention, and realize automation; 

5. Kiln head and tail sealing device: three-layer flexible sealing (stainless steel sealing scale + carbon silicon aluminum fiber composite board + stainless steel sealing scale) combined with labyrinth structure sealing, low air leakage rate, better sealing performance and higher reliability. Moreover, the service life is longer and the replacement is convenient, which can significantly reduce its maintenance cost. 

Let's walk into the installation site to see what the Φ 4.2×76m rotary kiln looks like? How to choose the right manufacturer for investing in coal gangue projects, it must be fully qualified, with manufacturers integrating design, processing, production, manufacturing, installation and after-sales.
