Flexicon bulk bag unloader with dual screw conveyors

Flexicon has released a bulk bag unloader with dual flexible screw conveyors that feed two downstream processes dust-free.

The BULK-OUT BFF Series Discharger features top-mounted receiving cups and a removable bag-lifting frame for forklift loading of bulk bags. Z-CLIP strap holders allow rapid, secure insertion and removal of bag straps from the lifting frame at floor level.

The bulk bag/hopper interface comprises a manual SPOUT-LOCK clamp ring for high-integrity bag spout connections, and a pneumatically actuated TELE-TUBE telescoping tube that exerts continuous downward tension on the clamp ring and bag spout as the bag empties and elongates, promoting flow and evacuation. Additional flow is afforded by FLOW-FLEXER bag activators that raise and lower opposite, bottom sides of the bag at timed intervals into a steep V-shape, and top-mounted POP-TOP extension devices that elongate the entire bag, promoting total discharge with no manual intervention.

The hopper is equipped with dual flexible screw conveyors that 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.
