ABSTRACT:
In a centrifugal separator, the rotor of which has a separation chamber (7) with an inlet (16) for a liquid mixture, a constantly open central outlet (23) for a separated liquid and an intermittently openable peripheral outlet (13) for separated solids, a so-called displacement liquid is supplied to the separation chamber (7) before the peripheral outlet (13) is opened first at a certain flow rate and then at a substantially lesser flow rate. If displacement liquid is sensed in the separated liquid leaving the rotor through the central outlet (23), the peripheral outlet (13) is opened.
