Abstract
An improved method of centrifugally separating, cleaning or classifying solids contained in a fluid flow delivered to a hydrocyclone 2 through inlet 28 wherein the removal of unacceptable material, i.e. rejects, is enhanced and the loss of acceptable material in the rejects is reduced by introducing a secondary fluid having a solids content of less than about 0.2% by weight into the separating chamber 24 through inlet 38 in a substantially helical swirling flow pattern coaxially about the vortex formed by the solids containing flow. An additional flow of low-solids secondary fluid is introduced into a secondary separating chamber 64 disposed at the apex end of the hydrocyclone 2 to receive the rejects flow from the primary separating chamber 24.
