CERAMIC WEAR LINER
Alumina Tiles And Composite Liners
Our ceramic range has three different alumina composition (92%, 95% and ZTA) products to suit the various mining applications.
Composite Ceramic Liners & Mats
REXLINE™ ceramic wear liners range include composite ceramic liners or Steel backed and studded as per requirements. We also have a range of molded ceramic in rubber with CN backing. The liners can be customized depending on the application.

History of Previous Liner
Previously installed Weld Overlay Liners were experiencing irregular and frequent wear requiring in-site repairs and change out of liners
Refurbishment
During refurbishment, 32mm Weld Overlay Liners were kept in the non-impact zone while REXLINE™ ZTA Ceramic Liners were installed in the main impact areas
Update – September 2016
Following the first inspection after 3 months the most wear measured was 1.5mm in the centre impact zone
Update – April 2017
Following the second inspection after 9 months the most wear measured was 8-10mm in the centre impact zone
Summary & Service Life
ZTA Liners performed exceptionally well compared with the previous chrome overlays installed which is not suitable for this application. The newly installed ceramic liner lasted for 13 months.
