Abstract

A method and apparatus for separating mixtures of different densities into a lighter phase and a heavier phase including a rotary drum providing a cylindrical settling sump at the outer wall, a displacement member rotatably located within the drum forming a settling sump between the displacement member and the drum wall, a discharge element for lighter phase material spaced radially inwardly from the settling sump, a discharge conductor for heavier phase material leading from the settling sump at the deepest location at the outer circumference of the drum, and a compressed air conduit connected to the discharge for heavier phase material aiding in the removal thereof, and vanes on the displacement member aiding in movement of the material through the drum.
