Previous Problem

Our customer is one of the world’s leading heavy building materials companies, producing aggregates, including stone, gravel and sand, to premixed concrete for use on residential, commercial, civil or industrial projects.

Our customer uses a wok style apparatus to mix the bulk cement preparation, ready for transit in mixer trucks. The wok lining experiences a narrow and concentrated impact area, handling high volumes of highly abrasive aggregate and sand particles.

At the Dandenong site, Kinder Australia’s ceramic wear lining panels were supplied by a different supplier and trialed as a way to conserve the steel walls of the wok structure.  However due to the concentrated high volume impact of the abrasive aggregate, the tiles became broken or dislodged.

This failure was also due its adhesive method of installation best suited to flat and level lining requirements. The curved surface of the wok compromised the bond of the ceramic, causing buckling.  This very quickly then lead to the individual ceramic modules peeling off the lining backing.

As an interim lining, a high quality rubber lining was then installed by the same supplier, which began to show even higher levels of erosion after a short time in use.


Given the curved nature of the wok, 8 panels of K-Superline® Polyurethane Lining Sheets were water-cut to precise measurements with a pattern of bolts replicated on each sheet.

The bolt-on design of K-Superline® Polyurethane Lining Sheets has the potential of allowing worn areas to be swapped and manoeuvred with other less worn sheets. In a confined space, this can be done quickly and without the need for welding equipment.

K-Superline® Polyurethane Lining Sheets has now been installed at the Dandenong site for 5 months and is showing no signs of wear. K-Superline® Polyurethane Lining Sheets has exceeded our customer’s expectations of its durability potential.
