The Main Role of Rotary Cement Kiln in Calcining Cement

Cement rotary kiln, as a main equipment of cement clinker dry process and wet process production line, has unique features. Temperature is high, and the flame temperature is at 1700-1900 ℃. Large clinker rotary kiln can be as high as 2100 ℃, and the material temperature is 1450 ℃. Almost all of various compounds in the stove can be dismantled, non-volatile elements through solid or through liquid phase forms clinker mineral phase or into the clinker mineral crystal lattice, and small amounts of volatile elements is with the flue gas escaping to the circumgyrate cement kiln after cooling down in low temperature area, only a tiny part as the steam state or adhering to the fine dust on the net with flue gas discharges.

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

1. 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.

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

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

3. as fuel combustion device

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

4. 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.
