Gravimetric Bulk Bag Discharger
Flexicon Europe Ltd (Herne Bay, Kent, England) has announced the launch of a new automated bulk bag discharger, equipped with an activated surge bin and flexible screw conveyor that allow loss-of-weight (gravimetric) discharging directly from bulk bags. Cubic volume of the activated surge bin exceeds that of one full bulk bag, providing ample time for bag changes during which system software switches to volumetric mode for uninterrupted operation.
The bag-to-surge-bin interface consists of a Spout-Lock(tm) clamp ring positioned above a pneumatically actuated Tele-Tube(tm) telescoping tube, allowing dust tight connections and unrestricted flow between the bag spout and activated surge bin, as well as automatic tensioning of the bag as it empties to promote flow and evacuation. The telescoping tube raises the clamp ring assembly that seals the clean side of the bag spout to the clean side of the tube and then lowers until the bag spout is pulled taut. Once the spout is untied, the telescoping assembly exerts continual downward tension on the spout, elongating the bag as it empties.
The high integrity, dust tight seal between bag spout and clamp ring allows full-open discharge from bag spouts of all popular diameters, says the company, eliminating the need for iris valves commonly employed to lessen dust escape inherent with bag spouts hanging loosely in hopper intake chutes.
