PCT No. PCT/DK90/00345 Sec. 371 Date Jun. 23, 1992 Sec. 102(e) Date Jun. 23, 1992 PCT Filed Dec. 27, 1990 PCT Pub. No. WO91/09680 PCT Pub. Date Jul. 11, 1991.A decanter centrifuge including a drum that is rotatably journalled at its ends includes a separating compartment defined by end walls and a rotatably journalled conveyor disposed in the separating compartment and rotatably journalled in two bearings, one located at the free end of a trunnion projecting into the conveyor body. The separating compartment has a length to diameter ratio greater than four and the trunnion has a length in the range from 0.5 to 3 times the largest diameter of the separating compartment. Due to the short distance between the conveyor bearings, the rigidity of the conveyer increases, thereby increasing the critical RPM of the drum.
