Abstract
Discharge nozzles are provided in centrifugal separator drums for the continuous discharge of the concentrate separated in the drum, and are inserted into the drum wall from the outside for the sake of ease of installation and cleaning. To enable the discharge orifice to aim itself correctly tangential to the drum circumference during operation and against the direction of rotation of the drum, there is provided opposite a locking projection on the discharge nozzle, an additional, excentrically disposed projection. The center of gravity of the rotatable discharge nozzle lies in this projection, so that, under the action of centrifugal force when the drum is rotating, the center of gravity of the discharge nozzle will set itself, even if incorrectly aligned at installation, on an axis that is radial to the drum axis. The discharge orifice is aimed opposite to the direction of drum rotation at an angle of 90.degree. to the gravity axis.
