ABSTRACT:
A method and apparatus for separating a hydrous slurry into overflow and underflow fractions which have particles differing in settling velocities. When applied to slurries of natural sand the invention provides an overflow containing fine sand particles and an underflow containing coarse sand particles. A barrier is employed having openings through which water flows upwardly with jetting action to provide a separating action in which coarse solids pass downwardly and fine particles progress upwardly. The apparatus is constructed whereby the slurry is introduced tangentially into the space above the barrier to cause continuous swirling movement of the material.
