Arrangement for separating off undesired particles from a suspension stream. The arrangement has a closed housing with an inlet for the suspension from which particles are to be separated off, an outlet for the treated suspension and an outlet for undesired particles. The arrangement also includes a screening drum that is perforated by a number of circular slits and cleaning members that are disposed inside the housing. The screening drum is immovable and the cleaning members are arranged to rotate along a circumferential surface of the screening drum and down into the circular slits.
