The device has a synchronous gear (3) staying in effective connection with a drive motor (1') and including output shafts (4, 5). Unbalance units are arranged in a horizontal direction between side walls (6') of a sieving body (6) and has horizontal shafts that are supported at a crossbar (21) by bearing units. The unbalance units are directly arranged at the horizontal shafts. The bearing units are exclusively arranged at the horizontal shafts in an axis direction of a shaft section between the unbalance units and supported at the crossbar.
