ABSTRACT:
The invention disclosed is control equipment for use with a nozzle centrifuge for separating a light phase liquid, a heavy phase liquid, and/or solids from a mixture thereof wherein the separated heavy phase and solids are continuously removed through nozzles that are arranged at the periphery of the rotor of the nozzle centrifuge. Separated light phase liquid is discharged through a central outlet in the rotor. Through a space in the rotor, which communicates with the radially outer part of the rotor separating chamber, liquid may either be supplied under pressure to the rotor or be discharged from the rotor far maintaining an interface layer formed in the separating chamber between separated light and heavy phases. A supply device and a discharge device are adapted to supply to the rotor and discharge from the rotor, respectively, only so much liquid as is required for the purpose. The discharge device is separated from the supply device, so that discharged liquid need not be subjected to the pressure generated by or maintained in the supply device.
