Halley & Mellowes will unveil the AeroTech ceramic bonding process developed by its Greenbank Terotech division on Stand 4905 during AIMEX 2007 – Asia Pacific’s International Mining Exhibition, to be held at Sydney’s Olympic Park from September 4 to 7, 2007.

This process produces components with the wear resistance of ceramic and the impact resistance of steel, and has proven itself in applications such as high-speed dynamic fan blades in the dust extraction and cement industries.

The lined item can flex without compromising the bond integrity. When alumina ceramic lining is used, weight can be reduced as the AeroTech process allows steel thickness to be replaced by ceramic, which is 50% lighter.

AeroTech provides a major break through in the lining of chutes, where continuous pounding and vibration has in the past led to delamination of ceramic from the steel backing material.

Standard epoxy adhesives do not provide full transfer of support from the substrate material, and the bond is unable to maintain adherence. As a result the ceramic cracks, dislodges and fails prematurely. AeroTech overcomes this problem and allows the full thickness of the ceramic liner to be used, increasing operating life and providing a more predictable maintenance life cycle.

AeroTech has been successfully been applied to pump volutes, mill paddles and mixer blades, valve gates, cyclone linings and screw conveyors.

Greenbank Terotech offers an engineering and design service that helps businesses to employ the AeroTech lining process to increase equipment operating life and reduce maintenance costs.
