Abstract

A method and an apparatus for centrifugally separating and classifying a liquid slurry into a solids heavy phase and a light phase fraction with a rotary mounted centrifugal drum having a cylindrical section extending from a first end and completed by a conical section extending toward a second end, a rotary auger within the drum moving slurry from the first to the second end, a slurry inlet at the first end; outlet nozzles extending at an oblique angle opposite the rotational direction of the drum in the cylindrical section for discharge of the heavy phase material, and light phase openings at the second end in the conical section close to the drum axis.
