Title:
UNITARILY-FORMED GRIT CLASSIFIER TANK AND BEARING
Document Type and Number:
WIPO Patent Application WO2002018028
Kind Code:
A3
Abstract:
A grit classifier of the type used in a variety of industrial applications to separate grit or particular matter from a feed slurry is disclosed, the grit classifier being unitarily-formed in one or two pieces of moldable plastic or plastic-like material which renders the grit classifier more easily and cost-effectively manufactured in comparison with conventionally-made grit classifiers. The grit classifier of the present invention is also advantageously easy to transport to a site, thereby further reducing the costs of use as compared to conventional grit classifiers of metal construction. Also disclosed is an auger bearing assembly for use in the unitarily-formed grit classifier tank of the present invention which is simply structured and adaptable to any screw auger type or size.
