ABSTRACT:
A disc screen having rows of rotatable discs separated by sleeve-like spacers. Discs of adjacent rows are offset and extended to a near touching relationship with the spacers of adjacent disc rows. A supporting and rotatably driven shaft extended through each row of disc and spacers. The spacers are independently mounted to the shaft with internal strengthening gussets having keyway-type openings slidably fitted to the shaft's non-circular cross section. End discs on each shaft are mounted for close proximity to the side rails of the disc screen housing and, as aligned along the side rails, are reduced in diameter to prevent interference. The proximity of the end discs to the side rails prevent materials from being jammed against the side rails.
