ABSTRACT:
Apparatus and a related method for facilitating and controlling the flow within, and out of a particulate matter bulk storage facility is provided. The apparatus includes a pre-shaped member, preferably in the form of a substantially impermeable plate, held within the storage facility, in a substantially horizontal orientation, above a discharge port. The pre-shaped member is of a predetermined size and shape and is located at a predetermined height above the discharge port. A vibrator unit is attached to the pre-shaped member and preferably supplied with power transmitted through a flexible conduit which does not restrict the motion of the vibrator/pre-shaped member combination. Operation of the vibrator causes the pre-shaped member to oscillate thereby creating moving voids and shock waves within the stored material which promotes an even velocity profile across the storage facility and produces a mass flow unloading pattern. The system minimizes bridging, coring, arching and ratholing, supports a central core of the stored material above the discharge port, and significantly reduces normal weight forces acting on adjoining material transport equipment.
