The telescoping tuberaises the clamp ring assembly that seals the clean side of the bag spoutto the clean side of the telescoping tube, and then lowers until the bagspout is pulled taut. Once the spout is untied, the telescoping assemblyexerts continual downward tension on the spout, elongating the bag as itempties.The high-integrity, dust-tight seal between bag spout and clamp ringallows full-open discharge from bag spouts of all popular diameters,eliminating the need for iris valves commonly employed to lessen dustescape.The discharger is also equipped with FLOW-FLEXER® bag activators that raise and lower opposite bottom edges ofthe bag at timed intervals, loosening compacted, non-free-flowing materials and promoting material flow into thebag discharge spout. As the bag lightens, the stroke of the bag activators increases, raising the bag into a steep "V"shape, eliminating dead spots for total evacuation of material with no manual intervention.The activated surge bin is isolated on rubber mounts and vibrated with an imbalanced weight gyratory motor,promoting uninterrupted flow into the small surge hopper of the flexible screw conveyor whose screw rotation speedis continually varied to maintain a pre-selected gravimetric discharge rate.The conveyor handles both free- and non-free-flowing bulk materials including products that pack, cake, plug, seize,smear or fluidize, with no separation of blended products.The BFC Series discharger is equipped with an optional raised operator platform (not shown), and a cantileveredI-beam with electric hoist and trolley for positioning bulk bags. Also offered is a BFF Series discharger with baglifting frame for forklift loading of bags.The unit is available in carbon steel with durable industrial finish, or stainless steel to industrial, food, dairy orpharmaceutical standards.*Patent(s) granted and/or pending.
