ABSTRACT:
A worm centrifuge system is disclosed wherein a rotatably supported centrifuge drum is provided together with a conveyor worm rotatably supported within the drum. A drive motor is provided for the drum and a separate drive motor is provided for the worm. A centrifuge drum and conveyor worm are normally operated at different RPMs. The conveyor worm is driven by one of the motors through a planetary gear and a housing of the planetary gear is connected to the centrifuge drum. The other drive motor connects with the housing of the planetary gear by a belt system. A switchable coupling is provided to connect the input of the planetary gear to its housing during start-up and then selectively to disengage the housing from the input of the planetary gear after operating speed is attained and the other drive motor is energized. The maximum energy requirements for each of the drive motors is reduced, thereby reducing cost.
