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.
Claims13
A centrifuge sieve comprising:
- a centrifuge drum having an inner surface;
- a support arrangement bearing at the inner surface of said centrifuge drum;
- sieve rods secured at the support arrangement at least at two locations and extending in axial direction of the centrifuge drum;
- said sieve rods being formed of a wear-resistant hard material;
- connection means for fixedly connecting the sieve rods at one location with the support arrangement;
- and
- connection means provided at the other of said two locations between the sieve rods and the support arrangement in order to enable a mobility of the sieve rods in relation to the support arrangement only in the axial direction.
