ABSTRACT:
Process and apparatus for the separation of solid matter via flotation. The flotation process for the separation of solid matter from a suspension takes place via the utilization of centrifugal forces wherein the suspension is brought into rotation in a separating zone so that the floated components are particularly effectively routed to and concentrated at the center of the separating space, whereby, when viewed axially, floated components and the remaining portion of the suspension is guided in the same direction and out of the separating zone, with the avoidance of vortexes in the flow stream achieving particularly favorable separation effects. In addition, several apparatuses, for carrying out the process, are also set forth.
