The bottom suspension arrangement is attached to the screw conveyor assembly at its bottom end, and comprises a rigid, substantially L-shaped lever having one leg mounted at its terminal end on the bearing and having its other leg spaced from and extending along the upper side of the jacket. A suspension point is located at the terminal end of this other leg for the attachment of a suspension device, and the one leg overlaps radially with the open bottom end of the jacket. Brace plates interconnect the lever and the jacket and are mounted along a portion of the inner periphery of the jacket at the open bottom end thereof.
