METHOD AND APPARATUS FOR SPREADING AND DISTRIBUTING A SOLID OR LIQUID PARTICULATE MATERIAL

For separating a solid or liquid particulate material from a pneumatically conveyed flow of material and spreading and distributing the material, the flow of material is introduced, preferably after it has been set in rotary motion, into a centrifugal chamber (20) for centrifugal separation of the particulate, solid or liquid material which is collected in a buffer store from which it is flung out in a plane perpendicular to the axis of rotation of the centifugal chamber. An apparatus for such separation, spreading and distribution comprises a centrifugal chamber (20) operable by means of the flow of material in order to achieve the contemplated centrifugal separation. The terminal edge (25) of the circumference of the centrifugal chamber (20) serves as an overflow for establishing a buffer store and has a flow-retarding inwardly directed flange (25). A baffle may be provided around the terminal edge to intercept the material flung out and conducting the material, via hopper-like flow-retarding recesses, to different outlets provided around the terminal edge.
