Abstract
A disc screen or like shaft structure in which screen discs 25 and spacers 28 are connected together in modular relation. The spacers 28 support the discs axially and are formed of plastic to allow the discs to deflect from their radial plane and the plastic spacers have an outer metallic surround 30 which is of smaller length than the spacers to present a protective metallic outwardly facing surface but allow the discs 25 to deflect laterally. The assembly is placed under a predetermined end-wise compression and the module is mounted on a rectangular shaft 27 which is suitably supported for rotation.
