Abstract

A scroll screen centrifugal separator includes a distributor that is configured to receive slurry received from a feed conduit. The distributor is configured to deflect the received slurry to a screen of the scroll screen centrifugal separator. In some embodiments, the distributor may include a distributor that has a flat surface encircled by a lip or having one or more lips positioned on the flat surface, an inclined surface, or a declined surface that faces the mouth of the feed conduit. In other embodiments, the distributor may include a plurality of dam members for defining passageways through which slurry is passable through the distributor prior to being ejected to a screen of the separator. In other embodiments, the distributor may include a distributor plate that has a plurality of radial arms attached thereto that are configured to direct slurry to the basket with a rotational velocity.
