Star-shaped screening machine for screening e.g. peat, of domestic waste, has screening disks with pockets, and sleeve extending in pockets, where two disks are enclosed by freely rotatable sleeve, which is made of impact-resistant plastic

摘要

The machine has a set of shafts (10), which are rotatably supported in a frame, and screening disks arranged at the shafts in a torque-proof manner. The screening disks have two-sides projecting hubs (15), where two of the screening disks, which are adjacent to each other, adjoin the hubs, and are enclosed by a freely rotatable sleeve (20). The screening disks have lateral annular pockets (16), and the sleeve that extends in the pockets, where the sleeve is made of impact-resistant plastic. A bush (18) made of steel is provided between the sleeve and the hubs.
