QMX supply and install a wide range of Alumina Wear Resistant Tiles for wear protection of all areas such as Chutes, Silos, Feeders, Bins, Launders, Dutching, Tanks, Bunkers, Hoppers, Underpans etc.
Described as the material of the future, alumina ceramics is one of the hardest of all natural substances known to man. Under extremely abrasive conditions, no material can compete on a cost to life basis with it's extreme hardness and wear resistance. In addition, alumina ceramics has exceptional chemical, mechanical, thermal and electrical insulation properties and can be formed into any shape or size with various qualities for specific applications.
Weld-On alumina ceramic tiles are typically used in high temperature applications and are available in most sizes to suit your application on an ex-stock basis.
