Mounting frame for laterally tensioned screening fabric by means of tensioning rails in a more decker sieve boxes

摘要

The longitudinal sieve supports (4) which are provided at either side have interchangeable material guides (10) which at least over the length of one of the screen fields. The guides can be fixed to the side supports by screws (11). At the start of each screen field formed by the curved screen arcs (3) pairs of flow pointers can be provided to break up the flow of material. USE/ADVANTAGE - The material flow is spread out more evenly reducing uneven wear and ensuring accurate sieving and long service life of the screen mesh.
