Abstract

In a decanting three-phase centrifuge, the position of the paring disc within a paring pump chamber defined by a rotatable bowl is radially adjustable to provide a cut point between a heavy fluid phase and a light fluid phase of a slurry and thereby separate the two phases. At least one sensor senses a fluid parameter of the separated heavy fluid phase and/or the separated light fluid phase and outputs a fluid parameter signal representative of the sensed fluid parameter. The control unit is programmed to, on the fly; receive the fluid parameter signal; determine from the received fluid parameter signal whether the cut point is to be adjusted; and if the cut point is to be adjusted, automatically drive the actuator to radially adjust the paring disc and thereby reset the cut point on the fly while the centrifuge is operating.
