Abstract
A method and apparatus for separating, spreading and distributing a solid or liquid particulate material. The particulate material is pneumatically conveyed into a centrifugal chamber within a rotor (20) operatable by the flow of material for centrifugal separation of the particulate material. The terminal edge of the circumference of the centrifugal chamber serves as an overflow for establishing a buffer store and has a flow-retarding inwardly directed flange. A baffle may be provided around the terminal edge to intercept the material flung out and to conduct the material, via hopper-like flow-retarding recesses, to different outlets provided around the terminal edge.
Claims14
A method for spreading and distributing a solid or liquid particulate material which is supplied in the form of a flow of material pneumatically conveyed by a conveying gas, comprising the steps of directing the conveying gas containing the material into a centrifugal chamber in a separator having a buffer store and at least one exit point, centrifuging the material in said chamber to separate the material by centrifugation from the conveying gas, collecting the material in the buffer store, conducting the material from said buffer store to said at least one exit point in the separator, and flinging it out in a plane perpendicular to the axis of rotation of the centrifugal chamber.
An apparatus for separating, spreading and distributing a solid or liquid particulate material introduced into the apparatus as a flow of material pneumatically conveyed by a conveying gas, said apparatus comprising an inlet for the pneumatically conveyed flow of said solid or liquid particulate material, a rotor arrangement, and at least one outlet in said rotor arrangement, said rotor arrangement being positioned and arranged so as to separate said material from the conveying gas and distribute the particulate material into said at least one outlet, wherein the rotor arrangement is a centrifugal chamber having a circumference and in flow communication with said inlet, said chamber comprising a cylinder having a circumference and a terminal edge positioned and arranged to provide a buffer storage space from which the separated material is flung out in a plane perpendicular to the axis of rotation of the centrifugal chamber.
