To dilute a heavy fraction separated in a cyclone separator, the latter is provided with a duct for supplying the diluent while maintaining it in rotation around the separator axis, the supply duct having a discharge orifice located at a radial distance from and within a circumferential wall surrounding the separated heavy fraction.

From the vortex chamber of a cyclone separator, a separated phase enters a discharge chamber coaxial with the vortex chamber and through which this phase flows toward a discharge opening while rotating around the axis of the chambers, thus following a screw-shaped track. Retarding means of the screw type are arranged coaxially in the discharge chamber and locked against rotation, the pitch of the retarding means being reversed relative to the pitch of the screw-shaped track of the separated phase.

A discharge chamber of circular cross-section extends axially from the vortex chamber and has at one end an inlet from the vortex chamber and at the other end a bottom provided with an outlet, the discharge chamber also having a central axis around which the heavy fraction separated in the vortex chamber is rotated in one direction while passing from said inlet to said bottom, the outlet being located below the plane of the bottom. The bottom has an open discharge groove communicating with the outlet and leading therefrom with a gradually diminishing crosssectional area in said one direction along the circular side wall of the discharge chamber through an angle less than one revolution; and a covering disc is disposed in close parallel relation to the bottom plane and is movable around the central axis, this disc having a recess in its peripheral portion and otherwise covering said bottom substantially entirely.

A CENTRAL VESSEL IS SURROUNDED BY GROUPS OF HYDROCYCLONES ARRANGED ONE ABOVE ANOTHER, EACH HYDROCYCLONE FORMING AN ELONGATED VORTEX CHAMBER HAVING AN ACCEPT END PROVIDED WITH AN INJECT INLET AND AN AXIAL ACCEPT OUTLET, EACH CHAMBER ALSO HAVING AN OPPOSED REJECT END PROVIDED WITH AN AXIAL REJECT OUTLET. THE CENTRAL VESSEL FORMS AN ACCEPT CHAMBER COMMON TO AND COMMUNICATING WITH THE VORTEX CHAMBERS BY WAY OF THEIR ACCEPT OUTLETS. MEANS ARE PROVIDED AT THE REJECT ENDS OF THE VORTEX CHAMBERS FOR COLLECTING THE REJECT FROM THE REJECT OUTLETS, THE COLLECTING MEANS INCLUDING MEANS IN THE VICINITY OF THE REJECT OUTLETS FOR ENABLING DETECTION OF A CHANGE IN THE REJECT FLOW.

The apparatus comprises means for spraying a suspension upon one side of a strainer, and a device which at least in successive increments covers the other side of the strainer, thereby preventing clogging of the strainer.
