In the 1980s, due to the lack of technology and production equipment, the ∅2.5meters rotary kiln developed by CHAENG was launched into the market, which opened the way of developing and manufacturing CHAENG rotary kiln.

The rotary kiln is widely used in the fields of building materials, metallurgy, chemical industry, environmental protection, etc. It can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to the different materials processed.

Rotary kiln feature:

1.Supporting Device: it adopts advanced main shaft structure, automatic temperature measuring device and electrical heating device. And it has optional flow support.

2.Thrust roller: It has mechanical type and hydraulic type. The hydraulic thrust roller is equipped with advanced hydraulic controlling system.

3.Drive device: It has single drive or double drive. The adjustable-speed motor, DC motor or frequency variable motor control kiln rotation speed. And has features of reliable running and high efficiency.

4.Tyre shim: The shim under tyre has fixed type and adjustable type. The adjustable shim has features of simple structure, easy replacement and maintenance without any damage to shell.

5.Sealing device: Various types of sealing device are available for different kiln, such as cylinder tighten sealing, spring tighten sealing, graphite block sealing, spring graphite, fish scale type seal etc, which has good sealing effect. 

6.Kiln head hood: It has fixed type and flexible type.

In the early 21st century, CHAENG carried out technological transformation of traditional rotary kilns according to the constant changes in market demand. The new rotary kiln is more energy efficient and environment-friendly, with high degree of automation and good quality of finished products. It is widely used in many industries such as building materials, metallurgy, chemical industry and environmental protection.
