Abstract

A system and process for separating paper fibers from contaminants of similar lower specific gravities employ a reverse centrifugal cleaner (25) wherein the discharge port (30) for lights (rejects) is located at the apex of the conical cleaner body, and the discharge port (44) for heavies (accepts) is located upstream from the apex.
