APPARATUS AND METHOD FOR DEPOSITING PARTICLES |
摘要 |
A granule applicator for an apparatus and method for applying granules onto an asphalt-coated sheet moving in a machine direction with improved resolution and edge definition of the applied granule patches and blends. One embodiment includes a rotating drum having openings that connect the interior space and an exterior of the rotating member. A granule dispenser is mounted within the interior space of the drum for dispensing granules there. A belt wraps around a major portion of the outside of the drum leaving an uncovered area. As the drum rotates within the belt, the granule openings move between a position closed by the belt and retaining granules by centripetal force and an open position wherein the granules are flung from the drum to a substrate. Doors may be used instead of a belt.
