Patent number: 9907229Abstract: Granule conveying apparatus (12) comprising two screw conveyors (21,22) are provided. Each screw conveyor comprises flighting (26,36) mounted to a shaft (27,37) and a cylindrical volume (61,62) associated therewith. Each cylindrical volume (61,62) has a length defined by the associated shaft (27,37) and a diameter defined by the associated flighting (26,36). One end of each of said two screw conveyors meet at an elbow or junction (52) where the direction of material conveyance is changed. The conveyor shafts (27,37) are supported independently from one another. The shaft of one of said two screw conveyors intersects the cylindrical volume associated with the other one of said two screw conveyors at the elbow. The close proximity of the two screw conveyors at the elbow region reduces power consumption.Type: GrantFiled: July 5, 2013Date of Patent: March 6, 2018Assignee: AGCO A/SInventor: Jakob Bro Sorensen
