Abstract
A material separation screen includes multiple shafts mounted on a frame. Multi-diameter disc assemblies are mounted on the shafts and are configured to rotate and separate out different types of materials from a material stream. The multi-diameter disc assemblies include spacer discs that separately interlock together around the shafts. Compound discs are separately attached to the shafts next to the spacer discs. The spacer discs are made from a harder material than the compound discs to reduce spacer disc wear and to reduce the amount of material needed for fabricating the multi-diameter disc assembly.
