The support roller device is main supporting system in the rotary kiln. It supports the entire weight of the rotating part of the rotary kiln, and positions the cylinder in the radial direction. The support rollers are exposed to high temperature, impact, vibration, open air, etc. for a long time, which affects the material properties of the kiln and the operating state of each component. Therefore, the inherent quality requirements of the support roller are high. 

CHAENG makes research, development, processing and matching of steel castings for years. It has a mature technology in the production of rotary kiln support roller. 

The support roller made by CHAENG has significant advantages:

1. Large load bearing capacity and good continuous running performance

The support rollers produced by CHAENG are made of ZG55, ZG42CrMo and other high-quality materials, with high tensile strength and good impact toughness, which greatly guarantees the quality of the support roller, and has the advantages of large load bearing capacity and good continuous running performance.

2. Advanced process

CHAENG treats support rollers by normalizing and tempering. The surface hardness of the outer circumference of the support roller is higher than 200HB, the high temperature resistance is good, and the friction resistance is small, guaranteeing the quality of the rotary kiln support roller greatly.

3. Guaranteed internal quality

CHAENG has a complete testing and quality assurance system. Before leaving the factory, the company's professional testing team will carry out non-destructive testing of the support rollers to ensure the internal quality.

4. High cost efficiency

CHAENG is a well-known large-scale steel casting manufacturer in China. The rotary kiln support roller is directly sent to customers without intermediate sales channels, avoiding the high price caused by intermediate costs, saving production cost for customers.

Focusing on the production of large steel castings for more than ten years, CHAENG is able to produce support rollers according to customers’ drawings for various rotary kilns, such as cement rotary kiln, lime rotary kiln, kaolin rotary kiln and so on.
