The main role of cement rotary kiln is used for calcining of cement and lime. In cement production, cement rotary kiln is special equipment for high-temperature calcination cement and its main function has the following four aspects:

1, as fuel combustion device

It has a broad space and thermal field, and can supply enough air. Excellent combustion equipment guarantees that the fuel burns adequately to provide the necessary heat for cement calcination.

2, as the heat exchange equipment

It has a more uniform temperature field and can meet the cement clinker production process at various stages of heat transfer requirements.

3, as a chemical reactor

As cement clinker minerals formed at different stages of different needs, it can be phased to meet the requirements for heat and temperature of different mineral form, and also can meet the requirements of time for them.

4, as a conveying device, it has greater potential.

In addition to calcining clinker, rotary kiln also has these functions of the burning device, chemical reaction device and transmission device; it is actually complex universal thermal technology equipment.
