A part-conical section () for use as part of a separation chamber () of a hydrocyclone () is described. The part-conical section comprises: an upper end defining internal and external diameters and including an upper mount (); a lower end defining smaller internal and external diameters than the upper end, and including a lower mount (); and a side-wall () defining an internal passageway () along a fluid transport axis () and an external surface. The internal passageway extends from the upper end to the lower end and defines a radially-inward tapering portion with respect to the fluid transport axis, and a non-inwardly-tapering portion with respect to the fluid transport axis. The tapering portion extends from the upper end to the non-inwardly-tapering portion, and the non-inwardly-tapering portion extends from a narrow end of the tapering portion to the lower end. A spigot () and a hydrocyclone () are also described.

A cyclonic separator () comprises a separation chamber (), a feed inlet () leading into the separation chamber and an underflow discharge () leading from the separation chamber. The cyclonic separator further comprises a vortex finder which has an inlet end positioned in the separation chamber, an outlet end defining an overflow discharge, and a bleed opening () defined by the inlet and outlet ends of the vortex finder and through which a portion of an overflow stream can be bled from the vortex finder to remove oversized particles from the overflow stream.
