Abstract

Sieve for a continuous action centrifugal drier consists of a metal with holes or slats and a coating to give the slots a longer life. This coating is composed of very hard metal carbide(s) or oxides(s). The coating is produced by spring with particles at high temp. and supersonic speed. The prods. are esp. useful for treating abrasive minerals. In an example, a stainless steel sieve with 0.150 x 4 mm slots was given a 0.030 mm coating of tungsten carbide, chromium carbide and 5% Ni.
