Half Frame Bulk Bag Discharger offers total dust containment by eliminating upper frame components to lift and/or position the bag. Instead, the unit relies on the user's forklift or plant hoist to suspend the bag above the unit during operation. The bag-to-hopper interface consists of a Spout-Lock clamp ring positioned atop a pneumatically actuated Tele-Tube telescoping tube, allowing dust-tight connections and unrestricted flow between the bag spout and hopper, 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 telescoping 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, eliminating the need for iris valves.
