Abstract
A rotary centrifuge for the separation of substances at different density having an outer cylindrical housing and a worm within the housing and the worm and housing driven at different rotational speeds, the housing having an opening for the discharge of the heavier fraction with the opening controlled by an external control element preferably stationarily supported and connected by a linkage to a movable valve member for controlling the opening, preferably a ring which moves axially to change the size of an annular discharge gap between the ring and a circular discharge opening in the end wall of the drum, but the opening can also be in the form of axial radial facing openings controlled by a movable valve member.
