Abstract:
A cyclone adapted for use in a dense medium separation process comprising:an inlet chamber having a tangential raw material feed inlet; a vortex finder extending into the inlet chamber and defining a low gravity fraction outlet for a low gravity fraction of separated material; a conical section opposed to the vortex finder, the conical section extending and continuously converging from the inlet chamber in a direction away from the inlet chamber; an outlet chamber extending co-axially with the conical section and in a direction opposed to the inlet chamber; a high gravity fraction outlet for a high gravity fraction of separated material being disposed generally tangentially relative to the outlet chamber, wherein a bottom surface of the outlet chamber is planar providing an unobstructed flow path from the outlet chamber to the high gravity fraction outlet and wherein an unobstructed flow path is provided from an end of the vortex finder extending into the inlet chamber to the high gravity fraction outlet.
