Abstract

A cyclone for classifying materials has at least one vibrator attached to the downwardly tapering conical housing thereof to set up vibrations which interrupt the normal flow pattern of the downwardly swirling slurry of materials so that some of the smaller particles which would otherwise be trapped in the slurry are freed so that an increased amount of the smaller particles will move into the vortex created in the cyclone and thereby increase the operating efficiency of the cyclone. In a first embodiment, a conventional cyclone having a solid metallic conical housing is modified by having the vibrator attached to the periphery of the conical housing. In a second embodiment, an open-sided conical housing having a plurality of spaced apart longitudinal struts with the vibrator mounted on a strut which is configured to transmit vibrations to the metallic substrates of abrasion resistant liners mounted in the conical housing.
