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.

AGICO is a cement equipment supplier with more than 30 years of production and sales experience. We provide customers with all kinds of cement equipment as well as the entire cement production line. Cement rotary kiln is our hot-sale product, the output can reach 300-5000 t/d and the size is between φ1.9*39m to φ4.8*74m. If customers have special production needs, we can customize or adjust the parameters of the equipment.

We provide equipment design, manufacturing, transportation, installation, commissioning, operation training, and a series of services, with high equipment quality and guaranteed services. If you want to purchase, please feel free to contact us!

Highlights Of AGICO Cement Rotary Kiln

Our cement rotary kilns are suitable for a variety of production environments.

AGICO rotary kilns can realize fully automatic operation and instrument control.

The overall structure of the kiln head and kiln tail sections has been optimized to solve the problems of material return and dust leakage.

AGICO cement rotary kiln has a strong structure and stable operation. During the high-temperature calcining, materials are heated evenly and the clinker quality is stable.

Compared with equipment of the same specification, AGICO rotary kiln has an operating rate increased by 10%, output increased by 5%-10%, and heat consumption reduced by 15%.

The transmission system adopts new AC frequency conversion speed regulation technology, which has a large speed regulation range, high efficiency, high-speed regulation accuracy, energy saving, and environmental protection.

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.
