Bulk Bag Unloader
The Half Frame Bulk Bag Unloader offers total dust containment, economically, by eliminating upper frame components to lift and/or position the bag, instead relying 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.
