Date Sep. 12, 1985.A screening apparatus, particularly for screening valuable materials, domestic garbage, industrial garbage, bulky garbage, dry garbage, wet garbage, compost and/or problematic and dangerous materials, including inclined, open-ended bars capable of oscillatory movement arranged in a transport direction and forming at least two bar grating screens forming a stepped arrangement of bar grating screens with one screen located behind the other in the transport direction. The bar grating screens have bars that are tapered in the transport direction. The apparatus further includes an inlet portion and a preliminary distributor path for feeding in material upstream of at least the upper bar grating screen of the stepped arrangement. A screen frame accommodates the bar grating screens, the inlet portion and the preliminary distributor path. The inlet portion and the preliminary distributor path comprise approximately one third of the entire length of the screening apparatus. Rubber oscillating elements are provided on which the screen frame is mounted. An eccentric drive mechanism is provided for causing the screen frame to perform a circular oscillating movement with a large circular oscillating diameter of approximately 100 mm.</p> |
