Sieve and sieving apparatus for separating solids from a suspension

摘要

A plurality of parallel sieve bars are transversely spaced apart in a plane to form a sieve. Each sieve bar has a side face enclosing an angle with the plane and diverging therefrom in the same direction so that the side faces constitute a stepped surface on said one side of said sieve. In sieving apparatus, such a sieve is arranged with said sieve bars spaced apart in an inclined plane and all side faces are disposed on the upwardly facing side of the sieve so that the angles of inclination of the side faces decrease progressively in groups of bars or from bar to bar.
