Device i.e. trommel, for granulometric separation of products from e.g. papers in industrial sector, has shuttle conveyor whose movement varies interruption of product distribution by intercepting products based on conveyor's position

摘要

The device has a rotative cylinder perforated with openings whose size longitudinally increases. A shuttle conveyor (44) is installed vertical to the cylinder. The conveyor is moved on a support along rectilinear translation in a plane formed by an axis of the conveyer and a rotation axis of the cylinder by a mechanical device. The movement of the conveyor varies the interruption of granulometric distribution of product flow by more/less intercepting the products issued from fall of the products across the openings in an area (24) of the cylinder according to a position of the conveyor.
