Case Study: Ceramic Rubber Liners Installed in Coal Transfer Chute of Indonesian Power Plant

2026-03-12

A coal-fired power plant in Indonesia experienced severe wear problems in the transfer chute of its coal handling system. Due to continuous coal impact and sliding abrasion, the original steel liners required replacement every six months.

Frequent maintenance not only increased operational costs but also caused unwanted production interruptions.

To solve this issue, the plant installed ceramic rubber composite liners designed for high-impact environments.

The liners featured the following specifications:

Parameter	Specification
Ceramic Material	95% Alumina
Ceramic Thickness	10 mm
Rubber Thickness	7 mm
Steel Plate Thickness	6 mm
Total Thickness	23 mm

The ceramic layer provided excellent abrasion resistance, while the rubber layer absorbed impact energy from large coal particles.

After installation, the liner's performance improved significantly. Even after one year of continuous operation, the liners showed only minor wear.

Customer Feedback

The maintenance team reported that the service life of the chute liners increased more than three times compared with the previous steel liners.

Conclusion

By adopting ceramic rubber composite liners, the power plant successfully reduced maintenance frequency, minimized downtime, and improved the reliability of its coal handling system.
