Abstract

A centrifugal type cleaner or separator, the separating chamber of which is provided, in its interior, with a sudden and sharp reduction of its cross-sectional area by means at the outer periphery of which is an escape passage for the deflected portion of a vortex type flow. The arrangement provides that as a slurry is moved through the chamber in a vortex type flow, the outer portion of the flow including the larger and lighter solids in the slurry, it is intended to reject, will be deflected to the escape passage while the remaining heavy and small solids will find an exit through the underflow nozzle of the cleaner. In the preferred embodiment here illustrated the escape passage is designed to maintain a vortex type flow pattern for the escaping material.
