Abstract
A centrifuge conveyor is provided with improved hard surfacing wherein assemblies of backing members and wear-resistant members are welded by the backing member to the conveyor. An assembly may be made unitary by providing a hole in either or both of the wear-resistant member and the backing member and securing them with means extending through the hole or holes. In the event that repair is necessary, an individual assembly may be replaced by welding technique, or the backing tile may be left in place and only the wear-resistant member replaced by removing and replacing the securing means. Each fragile wear-resistant member is braced against deflection at its outer portion through its backing member to the conveyor. The embodiments employ a plurality of wear-resistant members, each such member being accurately pressed from sintered tungsten carbide.
