ABSTRACT:
A granular material conveying system for conveying granular materials and filtering fine particles from the granular materials is configured for rotatably conveying granular materials about an axis in a longitudinal direction along the axis. The system includes a hollow center tube coaxially centered about the axis. The center tube includes an outlet, an exterior, an interior and a plurality of perforations communicating between the exterior and the interior. As the granular materials are rotatably conveyed along and around the center tube, fine particles from granular materials migrate through the perforations into the center tube and are thereby filtered from the granular material.
