Abstract (en)

[origin: EP0602557A1] The invention relates to a feeder, in particular for the classifying of heavy and fine fractions from a stream of fluid and solids operating with circulated air. This takes place by baffles (4, 5), which are arranged in the stream of fluid and solids to form a suction-removal duct, and by an air-distributing device (6, 7), which is arranged in the stream of circulating air. <IMAGE>
