Abstract
In the sieve drum device, a screen cover is not arranged, as customary, horizontally with sieve drums located, for example, in side-by-side relationship, but rather concentrically surrounds the respective sieve drum in the region covered by the material. In order to facilitate cleaning of the screen cover, the cover is swingable swung about a joint arranged on an axis in parallel to the sieve drum axis.
