The Rotary Kiln is the key equipment of cement clinker dry -process and wet -process production line, and is also used in various industries such as metallurgical , chemical industry ,building refractory ,environ mental protection industry , etc . The kiln is composed the cylindrical shell ,roller supporting device ,supporting device with thrust roller ,driving gear unit moveable kiln head ,sealing device at kiln inlet ,coal dust pipe device etc. The kiln shell is designed to keep some inclination to level .It is supported by the roller supporting device and equipped with thrust roller device to control the up and down moving of the shell .The driving system is equipped not only the main driving gear unit but also the auxiliary driving used to keep the shell rotating even when the main power is broken so as to prevent the shell from any bending and distortion .As the kiln head and tail are sealed by advanced technology ,the sealing of the kiln is fairly reliable.

Features
1、advanced structure, low loss can improve the vertical preheater preheating, the preheated limestone into the kiln after the decomposition rate of up to 20-25%, and the direct use of 10-15mm fine grade limestone;
2、reliable rotary seal both ends of the scales combined. Leakage coefficient is less than 10% of the composite refractory material used to reduce radiant heat loss;
3、filling, can be round or square partition vertical air cooler, resorted to the lime cooler temperature of 800C + ambient temperature, to facilitate transportation, storage, and the secondary air into the kiln preheated to 7000C or more, reducing the moving parts and special materials.
