Abstract
The novel invention proposes a final screen which is very reliable in operation and which is suitable more particularly also for building into a pneumatic conveying line. In a first section the material is distributed uniformly over the entire peripheral surface of the screen shell. The subsequent section is used for completing screening and separating the coarse material out through an outlet. A centrifuging rotor with helically arranged elastomeric cleaning lobes projecting from the centrifuging bars provide a high throughput and particularly damage-obviating discharge of even relatively large foreign bodies.
