BELT ELEVATOR WITH LATERALLY STIFF BELTS

摘要

BELT ELEVATOR WITH LATERALLY STIFF BELTS 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 change of elevation zone where the belts are held in face-to-face contact solely by opposed sets of edge rollers and a material delivery run of the other belt where the material is discharged at a different level. The belts are of sufficient lateral stiffness so that only the opposed sets of edge rollers are required to hold the belts in proper thrust transmitting engagement with the material being conveyed to a different level. Auxiliary fluid pressure means are not required to maintain the belts in proper engagement with the conveyed material in the change of elevation zone.
