Abstract:
A shaft for a rotary star screen apparatus has a shaft body having a series of axially spaced star connectors and a series of stars, mounted to the star connectors. Each one of these stars has a plurality of circumferentially distributed star members each elongate in a direction having a component radially away from the shaft body. The star connectors each have a plurality of circumferentially distributed star member connectors. Each of these star members is a separate part, individually and detachably mounted to one of the star member connectors. An apparatus equipped with such shafts is also described.
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.
Abstract:
A sorting screen for sorting material comprises a row of rotatable, driven shafts mutually spaced in a conveying direction. Each shaft extends transversally to said conveying direction and carries carrying a row of radially extending rotor bodies for intermittently urging material on the sorting screen upward and in conveying direction. The rotor bodies of each of said rows are mutually spaced in longitudinal direction of the respective shaft by spacers. Each spacer is a tubular spacer and each rotor body is provided with at least a recess or a number of projections retaining a respective end face of a respective tubular spacer.
