摘要

The device includes a screening unit (10) having rotating screening elements (13) arranged on multiple screening shafts (14) directed parallel to one another. The screening shafts are divided into two groups which are arranged alternately. The screening shafts of one group can be moved together and cross-axially in relation to the screening shafts of another group. The screening elements form a screening plate (21).
