Fibers from the dryer are getting accelerated by a horizontal air stream in inlet section and spread in Zigzag section. Vortexes, caused by zigzag shaped internals, separate coarse from fine material. Coarse particles fall down to sifter bottom section and get transported out by two screw conveyors. Accept-able material gets carried upwards and out of sifter to a high efficiency cyclone above the forming sta-tion. There, the material is separated from the air flow and discharged by an air lock.
