Rotor body for a sorting screen apparatus for sorting waste

摘要

A rotor body (3) for a sorting screen has an outer circumference with a plurality of radial projections (4) circumferentially distributed around a central axis of rotation and projecting radially outwardly from the axis of rotation relative to intermediate recessed portions of the outer circumference. The rotor body has a central portion of a first material and at least outermost parts (8) of the radial projections are of a second material. The first material is more elastic than the second material. A sorting screen including such rotor bodies is also described.
