What Is Cement Rotary Kiln
Cement rotary kiln, also called cement kiln, is a pyroprocessing device used for calcining cement clinker in cement production lines. It is the main engine in the cement manufacturing process, commonly known as the “heart” of the cement plant. In the production process, an equipped kiln burner produces heat by burning fuel, and the heat is transferred to materials through flame radiation, hot gas convection, kiln brick conduction, etc., which promotes the chemical reaction between cement raw materials and finally forms clinker.

How Does Cement Rotary Kiln Work?
On the cylinder, there is a large girth gear ring fixed with a spring plate near the kiln tail, some pinions below are engaged with it, jointly forming the drive gear. In normal operation, the main drive motor transfers power to this gear device through a reducer to run the rotary kiln. The raw material usually enters the rotary kiln from the kiln tail and moves slowly to the kiln head along with the chamber as it rotates. In this process, raw materials are heated by high temperatures and decomposed, producing chemical reactions. The heat source of rotary kilns is supplied from the kiln burner inside the kiln. Besides, the rotation speed and temperature of the cylinder are tightly controlled and changed according to different processes and applications. After the calcination is completed, the clinker will be pre-cooled in the chamber and then sent into the cooler for further cooling.
