ABSTRACT:
A centrifugal cleaner has a cleaning quotient greater than 0.5 and a rejects by weight performance value typically of less than 5% (e.g. less than 2%) for conventional paper pulp furnish. The tangential inlet nozzle to the side wall near the top of the cleaner body has a non-circular--preferably D-shaped--inlet opening so as to provide enhanced throughput. The cleaner body side wall includes an upper portion that is conical and extends past the top nozzle, a generally cylindrical center portion which significantly increases retention time within the cleaner, and a conical bottom portion in which a bottom nozzle is operatively disposed. The bottom nozzle has a rejects opening therein with a diameter that is about 25-45% (preferbly roughly 1/3) of the internal diameter of the side wall at the opening, and is about 25-45% (preferably roughly 1/3) of the internal diameter of the top nozzle. The bottom nozzle may have an insert with an interior three-dimensional parabolic surface terminating at its bottom in the rejects opening, or may comprise a flat plate with a main top surface perpendicular to the top nozzle. During use rejects particles collect on the flat plate top surface and define a generally parabolic configuration.
