Preheater

Preheater made by CHAENG is classified as cement rotary kiln preheater and lime rotary kiln preheater.

Preheat capacity :200-600t/d
Brand :CHAENG
Material classification :cement, lime
Application :cement production line, lime production line

Preheater made by CHAENG is classified as cement rotary kiln preheater and lime rotary kiln preheater. When the vertical preheater is used with the rotary kiln, it can make full use of the waste heat of the high-temperature flue gas at the kiln end, which is energy-saving and environmental protection.

The main function of vertical kiln preheater is to transport the cement raw material or limestone from the upper into the preheater body, at the same time preheat material evenly with the furnace hot waste gas discharged after calcining. In the preheating process, some materials are decomposed in the preheater, and then are pushed into the rotary kiln for calcining by the hydraulic push rod. This calcination process not only makes the calcining time greatly shortened, but also obtains a high degree of cement and lime products.

Specification Quantity of push rod Height (m) Capacity (t/d) Feed size (mm)
YRQ-04 4 4 200 10~50
YRQ-06 6 4 300 10~50
YRQ-08 8 4.4 400 10~50
YRQ-12 12 4.4 600 10~50

1. Working under high temperature of 1000 ~ 1100 ℃, with long time;

2. The structure design is novel and the sealing is good, which can ensure that the material is preheated evenly in the preheater and reaches the preheating temperature.

3. The effective recovery of heat from the exhaust emission of the kiln tail increases the system fuel efficiency and also helps to remove dust.

4. When the calcining system adopts the vertical preheater, it reduces the heat dissipation of the rotary kiln and save space.

5. The use of the vertical preheater system can achieve good comprehensive benefits, the capacity can be increased by 30%, and the thermal efficiency can be increased by 40%.
