Working principle of cement preheater

  The preheater is one of the important equipment in the whole cement production line, its quality and management are directly related to the quality, efficiency and cost of cement calcining. As a professional equipment supplier for cement production line, Luoyang building Material and Architectural Design and Research Institute (LCDRI) has accumulated rich experience in the design and manufacture of preheater. Following will explain the main function of preheater.

The principle of preheater including following items:

1) Heat exchange: fully use the exhausted waste heat from rotary kiln and calciner to heat raw material;

2Material dispersion: feed the raw material into the preheater pipe, under the impact of the high speed rising air flow, the material turns on flow with the air, meanwhile the material will be dispersed;

3Dispersion plate: improve the effect of dispersion;

4Air lock valve: not only keep the material feed uniform and smooth, but also keep seal;

5The heat transfer between gas and solid: more than 80% heat exchange was happened in the inlet pipeline, and the convective heat transfer is the mainly heat exchange mode;

6Gas solid separation: the main function of cyclone is gas solid separation.

 

Luoyang Building Materials and Architectural Design and Research Institute (LCDRI), specialized in Cement Engineering Design (including turnkey project), moreover we have invented and developed many solutions and equipment which has been already applied in many projects and industries.
