Abstract
Arranged in the upper region of a drum which rotates about an axis there is a dust box for dust removal. The box is connected with a line, which leads outwards, by way of a laterally arranged discharge channel. Arranged between the dust box and a baffle rotor which rotates about the axis are baffle areas which form labyrinth-like passages for the dust to the dust suction openings in the dust box.
