回转窑是水泥熟料干法和湿法生产线的主要设备。回转窑广泛用于冶金、化工、建筑耐火材料、环保等工业。该回转窑由筒体，支承装置，带挡轮支承装置，传动装置，活动窑头，窑尾密封装置，喷煤管装置等部件组成。 回转窑的窑体与水平呈一定的倾斜，整个窑体由托轮装置支承，并有控制窑体上下窜动的挡轮装置，传动系统除设置主传动外，还设置了在主电源中源断时仍能使窑体转动，防止窑体弯曲变形的辅助传动装置，窑头、窑尾密封装置采用了先进的技术，保证了密封的可靠性。
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.
