Other particles (less than 1 mm) lift by air stream into a classifier where blades (4) make rotating dust flow. Middle size particles shift to wall by centrifugal force in a big chamber of a classifier and fall down to cone (6) and later they move into an accelerator (2). Small particles move by air stream to outlet (8).
