A hydrocyclone (1) comprising a vertical-axis separating chamber having an upper cylindrical portion (2) and a lower, coaxial conically-tapering portion (4b) has: a tangential inlet (3) at its upper end for a suspension (F) to be classified; an upper, axial outlet (8) for the overflow (O) containing finer particles separated in the hydrocyclone in use; a lower axial outlet (5) for the underflow (U) containing coarser particles; and a hollow spigot (7) projecting into the separating chamber from its upper end.. The separation of coarse particles from the overflow is improved by the provision of an extension tube (9) extending coaxially from the spigot into the separating chamber. |
