2. Low pressing loss
3. High decomposition ratio
4. Anti-blocking
5. Good sealing performance



Description:
Five-stage preheater is the heat exchange device in dry-process rotary kiln. The suspension preheater is used for heat exchange and seperation between dry raw powder and the hot airflow from rotary kiln. Suspension preheater is featured by excellent preheating effect, strong raw material adaptability, low system pressing loss, high in-kiln decomposition ratio, anti-blocking and good sealing performance. It can achieve preheat and partial decomposition for raw meal, replace some functions of rotary kiln and reduce the length of rotary kiln.

Vertical preheater system is mainly composed of six parts:
1. Upper feeding system: Mainly include upper storage bin and feeding pipe. The feeding mode and structure can ensure safe sealing while feeding materials into the preheater so as to prevent the external cold air entering into the preheater, and continuous interrupted feeding can be realized by using bar valve.
2. Preheater body: This is the most important part for ensuring that the materials can be heated to about 900 degrees Celsius. It is composed of preheating chamber, suspension system and refractory brick liner (this part is not included in the equipment design and manufacturing scope), etc. This part adopts most metal components and some heat resistant steel which can work in high temperature up to 1000-1100 degrees Celsius. In addition, the refractory brick liner is designed with excellent sealing performance, which can ensure that the materials can be heated evenly in the preheater and reach preheated temperature.
3. Pushing unit: This part is mainly composed of pushing head, frame and connection rod. The pushing head is made by casting or welding heat resistant steel which can bear high temperature. By using electronic control and hydraulic system, each hydraulic pushing rod can push materials in proper sequence in accordance with th e automatic control procedure.
4. Hydraulic system: This part is mainly composed of oil tank, oil pump, electromagnetic valve and hydraulic oil pipe, etc. It is mainly used for controlling the pushing unit to push materials.
5. Lower charging chamber: This part is mainly composed of chute, main body of charging chamber and charging chute mouth, and it is mainly used to lead the preheated materials into rotary kiln for calcination.
6. Frame: This part is mainly composed of vertical shaft and ring beams, using for bearing the upper structure of the preheater.
