Abstract
A disc screen with spacers of limited compressibility is disclosed which has an elongated metal shaft member with a plurality of screen discs mounted co-rotatively on the shaft member. The screen discs have central shaft receiving openings through which the shaft extends coaxially. The screen discs are separated and spaced on the metallic shaft member by a plurality of metallic nonresilient and nonmetallic resilient spacers located between and coaxial with adjacent screen discs. The preferred embodiment of this invention has two metallic spacers with one nonmetallic resilient spacer between them, with the group of three spacers being located between each pair of screen discs which are spaced along the shaft member. The nonmetallic resilient spacers, which are preferably polyurethane, function to allow limited tilting of the screen discs out of the plane perpendicular to the axis of rotation.
