<p>Apparatus and related method for facilitating and controlling the flow within, and out of a particulate matter bulk storage facility. The apparatus includes a pre-shaped member (26), preferably in the form of a substantially impermeable plate (26), held within the storage facility (10), in a substantially horizontal orientation, above a discharge port (22). The pre-shaped member (26) is of a predetermined size and shape and is located at a predetermined height above the discharge port (22). A vibrator unit (30) is attached to the pre-shaped member (26) and preferably supplied with power transmitted through a flexible conduit (34) which does not restrict the motion of the vibrator (30) and the pre-shaped member (26). Operation of the vibrator (30) causes the pre-shaped member (26) 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.</p> |
