Abstract: A belt conveyor for grain or other granular materials has an enclosed housing, a bottom return, an infeed end and a discharge head. The conveyor uses a special high angle lift belt with projecting lugs of approximately two inches high and having cooperating angled elements that form material receiving pockets. The lugs are arrayed on the belt in meshing relationship so that as the belt curls laterally within the housing, the lugs prevent backflow of materials at least up to a forty degree angle when the conveyor is running. The bottom return section of the conveyor has a plurality of belt supporting rollers extending transversely across the return section. The belt lugs are also arranged so that upper ends of the lugs form a longitudinally and transversely continuous supportive surface for low friction running support by the belt return rollers.
