Abstract: A disc for releasable attachment with a shaft of a disc screen apparatus. The disc separates into two opposed halves at a parting line having offset portions. The disc includes a hub with a bore for receiving a rotating shaft. The hub is radially offset about a center axis of the disc to generally correspond with the offset portions of the parting line. The offset hub distributes rotational forces on the disc to prevent separation of the discs during operation.
