ABSTRACT:
An elevator-conveyor for conveying bulk material over a predetermined path, at least a portion of which is in a vertical or near vertical direction, comprises a pair of juxtaposed belts between which the bulk material is to be located, and apparatus for applying air pressure directly on one or both of the outer belt surfaces when the belts are in the vertical or near vertical direction. The air pressure presses the belts towards one another and against the interposed bulk material so as to enclose the same; and at the same time, the juxatoposed longitudinal edge portions of the belts are pressed against each other to contain the bulk material. Apparatus is also provided for ensuring effective feeding of the conveyor and the mechanical sealing thereof against undesirable air flow. Provision is made for appropriate belts for use with the conveyor.
