ABSTRACT:
A solid shell screw conveyor centrifuge which includes a screw rotating at a differential speed with respect to the shell. One of the shell and screw is connected to a first hydraulic motor as a main drive assembly and to the other of the shell and screw by way of a second hydraulic motor having pressure medium supplied thereto by way of a rotary transmission. The first hydraulic motor functions as a drive assembly for the shell and also is operable as a pump with a discharge from the pump being controlled by way of a valve arrangement. The valve arrangement is disposed in a conduit connecting the hydraulic motor with a pressure medium conduit supplying pressure medium to the rotary transmission of the second hydraulic motor.
