Abstract
An improved multi-disc assembly and method for releasable attachment to a shaft of a disc screen apparatus. A multi-disc hub includes multiple discs configured for use in a material separation screen of a disc screen apparatus, and has a through bore configured for direct engagement over the shaft of a material separation screen. The multi-disc hub is comprised of at least two parts that detach from each other, and at least one part comprises a portion of the through bore cross-sectional area that is less than or equal to half of the total through-bore cross-sectional area. A fastener is adapted to attach at least one hub part to the shaft, and the fastener provides a force that is greater than the force of gravity to temporarily retain the hub part onto the shaft when the shaft is rotated.
