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 prelimin- ary 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.
