280 - 2500 TPD Suspension Preheater 5-Stage Preheater Cyclone in Cement Plant

Cement Preheater

The main function of cyclone preheater is to make full use of the thermal enthalpy of raw materials in the hot gas flow discharged from the rotary kiln and the rotary kiln, to preheat and decompose part of the carbonates, and then enter the rotary kiln and continue to heat and decompose to complete the calcining of clinker. Therefore, it must have the following three functions: sufficient dispersion and uniform distribution of gas-solid phase, rapid heat exchange, and efficient separation.

Cement Preheater Features:

1. High productivity: the cyclone preheater adopts multistage cycle suspension preheating to improve the production rate.
2. Low investment: due to the reasonable structure of cyclone preheater, reduce the problems of equipment, cost-effective, low investment and higher benefits.
3. Low energy consumption: make full use of heat in the kiln, reduce the energy consumption of clinker production, and reduce the room required.
4. Wide application: custom-design cyclone preheater can be provided according to different regions and production scale, turnkey project of preheater.

Working Principle

The material is lifted through the kiln bucket and enters the chute of part of the material on the top of the kiln. The rotary feeder enters the preheater at the end of the kiln from the feeding port on the c2-c1 air duct. The material in the updraft air duct is brought into the C1 cyclone tube. In the cyclone tube, the material is collected by the cyclone and enters into the c3-c2 air pipe through the C1 blanking tube. At the outlet end of the blanking tube, there is a charging device to evenly distribute the material in the updraft. In this way, the material and hot gas get full heat exchange. All processes above the C4 cyclone cylinder are similar to those described above. The decomposing furnace is a core equipment in the preheater system. It is equipped with four sets of coal spraying pipes, which are used to inject fuel into the decomposing furnace respectively with left rotation and right rotation. About 55-65% of the total fuel is burned in the furnace, which provides the ambient temperature for material separation. The fully heated and decomposed material enters the C5 cyclone cylinder with gas, and finally enters the rotary kiln through the feeding room. So the whole process is; Materials from top to bottom, high temperature gas from bottom to top, and the material heating and decomposition.
