Abstract

An apparatus for separating grain material and for sorting out heavy inclusions from a product flow, particularly stones from gain material, in which the product flow is fed to an inclined layering table and guided so as to be substantially layered thereon. The layering table being acted upon by air flow and oscillated in such a way that the heavy inclusions lying directly thereon are conveyed up the table and guided away separately at the higher end. The feeding of the product flow is effected by way of a feed duct which opens to into the area of the higher end of the table and feeds the product into the separating zone of the product layers as a flow across the widest possible surface area, the separating zone being located in the area of the higher end of the table. The table has air guides for circulating. On an upper side, a closed hood is arranged and on an end side, a product feed portion is arranged. In the middle thereof, an outlet suction portion coupled to the closed hood is arranged. The inclined layering table as well as the closed hood with the guides for the air outlet portion form an oscillating box which is closed on all sides.
