ABSTRACT:
A bulk material handling apparatus especially adapted for handling granular material wherein a pair of flexible belts are arranged about drive and idler pulleys to provide a material receiving run of one belt, a first transition zone where the pair of belts have edge-to-edge contact in a path curving from horizontal to vertical as defined by a plurality of edge rolls, a vertical change of elevation zone where the belts are held in face-to-face contact by opposed sets of edge rollers, a second transition zone and a material delivery run where the material is discharged at a different level. The edge rollers and rolls of the elevation and transition zones have parallel axes and cylindrical belt engaging surfaces whereby the belt edges are maintained in parallel, face-to-face contact and smoothly transfer between the zones without entrapping the elevated bulk material between the edges.
