Abstract
A separating screen conveyor for sorting a material into fractions having different distributions of a property of the particles or items. The conveyor screen has a row of shafts mutually spaced in a conveying direction, each shaft carrying a row of axially spaced discs for intermittently urging material on the sorting conveyor upward and in the conveying direction. The discs are releasably clamped to the shafts which have strips oriented in longitudinal direction of the shafts on circumferential surfaces of the shafts. The strips have toothed surfaces. Openings of the discs each have a recess closely fitting to the strips and teeth in engagement with the teeth of the toothed surfaces of the strips. The pitch of the teeth of the strips is smaller than the maximum widths of the discs in the longitudinal direction of the shaft.
