Flexicon has launched a new bulk bag unloader with dual flexible screw conveyors to feed to downstream processes without dust.
The BULK-OUT BFF Series Discharger uses top-mounted receiving cups and a removable bag-lifting frame for forklift loading of bulk bags. Strap holders allow rapid, secure insertion and removal of bag straps from the lifting frame at floor level.
The bulk bag/hopper interface is comprised of a manual clamp ring for high-integrity bag spout connections, and a pneumatically-actuated telescoping tube that exerts continuous downward tension on the clamp ring and bag spout as the bag empties and elongates, promoting flow and evacuation.

Bag activators raise and lower opposite sides of the bag at timed intervals to form a steep V shape while top-mounted extension devices elongate the entire bag to promote total discharge with no manual intervention.
The hopper uses two screw conveyors to transfer free and non-free flowing bulk materials to downstream processes separately or simultaneously.
The flexible screws are the only moving parts contacting material, and are driven beyond the point at which material is discharged, preventing material contact with seals.
The system is available in carbon steel with durable industrial coating, or stainless steel finished to industrial, food, dairy or pharmaceutical standards.
