Abstract
In a centrifuge sieve drum wherein the inner surface of the drum is lined with a support arrangement which carries wear-resistant sieve or screen rods formed of a hard material, there is obtained a compensation of the different thermal expansions of the sieve or screen rods and the support arrangement in that, the sieve or screen rods are fixedly connected, in each case, as by riveting or by a threaded connection, at one location with the support arrangement of the sieve drum, whereas the rivets or threaded screws at other connection locations are moveable in a slot-shaped or elongate hole in the axial direction of the sieve drum.
