Cyclone.

摘要

Disclosed is dense medium cyclone for separating particles of varying sizes from within a fluid stream. The particles to be separated are entrained within the fluid stream. The fluid stream is then introduced into a cyclone that includes a body and a side wall comprising an upper wall portion and adjacent lower wall portion tapering inwardly in a direction away from the upper wall portion. The cyclone further includes a vortex finder projecting substantially axially into the interior space through the upper end of the body and terminating at an internal end positioned below an inlet, the vortex finder defining an overflow outlet which removes the remaining fluid and entrained particles from the cyclone. The vortex finder and the upper wall portion are configured to define a feed zone of decreasing cross sectional area from the inlet to the internal end of the vortex finder.
