PCT No. PCT/DE97/00431 Sec. 371 Date Sep. 11, 1998 Sec. 102(e) Date Sep. 11, 1998 PCT Filed Mar. 4, 1997 PCT Pub. No. WO97/36686 PCT Pub. Date Oct. 9, 1997A centrifugal drum (1) has an inlet chamber (12) connected to a discharge chamber (10) via ducts (21), with the supplied fluid flowing radially through rib-free annular chambers (24, 25, 26) on the way to the discharge chamber (10). A through-flow resistance is thereby generated which ensures that the inlet chamber (12) is filled completely. Since the ducts (21) start in the vicinity of the inlet pipe (8), the acceleration of the supplied fluid to the speed of rotation of the centrifugal drum (1) occurs over a small diameter with the result that the stress on the centrifuged material is relatively low.
