Device for fractionating fibrous particles of different sizes

摘要

Beyond the controlled feed bunker (1) is a flat sieve device (19) and a feed unit (8) for the controlled feed bunker, via which the particles (3) are moved from the controlled feed bunker onto the surface of the sieve device (19). In the area of the surface of the sieve device, a transport device (10) is provided, with a number of separated apportioning sections (17) movable along the surface of the sieve device. Within the sections a part of the particles (3) fed from the feed unit (8) to the surface of the sieve device is displaceable over the surface of the sieve device.
