This skid-mounted bulk bag discharging system with positive pressure pneumatic conveying system transfers material from bulk bags to silos and other bulk storage facilities on islands or other locations unable to receive large volumes of bulk material by rail or truck. A cantilevered I-beam with electric hoist and trolley lifts and positions bulk bags. A Spout-Lock clamp ring forms a high-integrity seal between the bag spout and the equipment, while a Tele-Tube telescoping tube maintains downward pressure on the clamp ring and bag spout, elongating the bag as it empties/elongates to promote complete discharge. Material flow is aided by Flow-Flexer bag activators that raise and lower opposite bottom sides of the bag. A Bag-Vac dust collector dust-tight system creates a vacuum within the dust-tight system to collapse empty bags prior to retying and disconnection, eliminating dust emitted during manual flattening of empty bags.
