Abstract (en)
[origin: US4661244A] The invention relates to a rotary basket air classifier. A favorable predispersion of the material to be classified, particularly in the case of an upwardly directed spent classifying air line has always been problemmatical with such classifiers. According to the invention, the material to be classified is distributed over several stages, aided by dispersing blades and a higher drawing-off capacity of the spent classifying air is permitted by the branching of the drawing-off line.
