ABSTRACT:
A vibratory vertical lift conveyor including a vertically elongated, tubular lift assembly having an inlet at its lower end and an outlet at its upper end. The assembly is provided with generally L-shaped projections extending from end to end within the interior of the assembly to provide for material lifting action when the assembly is vibrating in a vertical direction. Additionally provided is a yieldable connection between the vibrator and the lift assembly to accommodate startup of the conveyor; a mulling sphere within the tubular assembly received therein for limited movement between the projections to mull particulate material passing upward in the assembly; a backflow preventing device at the inlet to preclude backflow of material within the inlet when the vibratory conveyor is moving downwardly; and a manifold and inlet for a treating gas for treating material as it passes upwardly within the assembly.
