Abstract

A rotary separator has a separation vessel comprised of opposed conical sections and has an annular gap between the sections for discharge of solid material. A sleeve surrounds the separation vessel and is attached to the lower conical section thereof by a flexible member allowing axial sleeve movement. The sleeve carries a ring for comovement therewith displaceable to open and close the gap. When the pressure of material in the vessel is sufficient to overcome the flexibility characteristics of the material supporting the sleeve, discharge occurs. The flexible member may be pre-stressed to control the pressure required for discharge to occur, or a chamber communicating with the sleeve and flexible member may be pressurized to selectively displace the sleeve and ring and thereby control discharge.
