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.

Project Overview

Industry Product Asset Location Installed Material Size Throughput ROI
Nickel Mine 95% Zirconia Toughened Alumina Tiles Chute 503 Western Australia August 2016 ≤600mm material passes through the underflow of the primary crusher and through to the primary stockpile TBA Replacing Overlay Liners with Ceramic Composite Liners

Location of Installation

Impact plate Chute 503 - 02

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.
