The BFF Series Bulk Bag Discharger is designed for operation in-line with pneumatic conveying systems and eliminates dust during untying, discharging, collapse, retying, and removal of bulk bags while increasing safety and promoting complete discharge of bag contents. The design features a new bag-to-conveyor interface comprised of two sections, the uppermost of which contains a Spout-Lock&reg clamp ring positioned atop a pneumatically actuated Tele-Tube&reg telescoping tube, allowing dust-tight connections between the bag spout and hopper, as well as automatic tensioning of the bag as it empties to promote flow and evacuation. BFF Series dischargers are characterized by top-mounted receiving cups and removable bag-lifting frames for forklift loading of bulk bags at low cost. Also offered are BFC Series dischargers having a cantilevered I-beam with electric hoist and trolley to raise and position bulk bags without the aid of a forklift. Both series of dischargers are fitted as standard with patented Z-Clip strap holders for rapid, secure insertion and removal of bag straps, and are available with integrated scale systems for loss-of-weight batching directly from bulk bags.
