The BFC Series of bulk bag dischargers is at the heart of an automated bulk bag weigh batching system that feeds ingredients to a central weigh hopper at mezzanine level using four flexible screw conveyors, and transports pre-weighed batches to a downstream blender using a pneumatic conveying system. The BFC features a cantilevered I-beam with electric hoist and trolley to raise and position bulk bags without the use of a forklift.
The units are equipped with Flow-Flexer bag activators that raise and lower opposite bottom edges of the bag at timed intervals, loosening compacted materials and promoting material flow into the discharge spout. As the bag lightens, the stroke of the bag activators increases, raising the bottom of the bag into a steep V-shape, promoting total evacuation of material from the bag with no manual intervention. Each discharger is equipped with a surge hopper discharging into an enclosed flexible screw conveyor.
