Flexicon mobile bulk bag discharger with manual dump station and screw conveyor

Flexicon’s latest mobile half-frame bulk bag unloader with multipurpose hopper allows material to be discharged from bulk bags, manually tipped from sacks, and conveyed to downstream processes and storage vessels dust free. For in-plant mobility, the system minimises weight and achieves a low centre of gravity by eliminating upper frame components, relying instead on the user’s forklift or plant hoist to suspend the bag above the unit during operation.

The bulk-bag-to-hopper interface consists of a Spout-Lock clamp ring positioned atop a 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.

An integral Bag-Vac dust collector creates negative pressure within the dust-tight system to collapse empty bags prior to retying and disconnection, eliminating dust emitted during manual flattening of empty bags. Flow-Flexer bag activators raise and lower opposite bottom edges of the bag at timed intervals, loosening compacted materials and promoting material flow into the bag discharge spout.

For manual tipping the operator raises a hinged bag-dump support shelf and a hinged hopper door, and pours material through a coarse screen into the hopper.
