Abstract
A method of separating solid particles present in a liquid in which the solid particles float by subjecting the liquid to centrifugal force in a chamber thereby causing the solid particles to move radially inwardly and produce a pack of solid particles while the liquid freed of solid particles flows radially outwardly; continuously withdrawing liquid freed of solid particles from the chamber; and continuously removing solid particles from the pack. Apparatus for centrifugal separation of solid particles from a liquid in which they are buoyant, comprising a chamber adapted to be rotated about an axis; a conduit to continuously feed liquid containing the solid particles to the chamber; a conduit to continuously withdraw liquid substantially free of solid particles from the chamber; and a scraper to continuously remove solid particles from a pack of solid particles which forms in the chamber as a result of centrifugal force when the chamber is rapidly rotated.
