Flexicon mobile half-frame bulk bag unloader

Flexicon’s 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.

The bulk-bag-to-hopper interface has 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 seal between bag spout and clamp ring allows full-open discharge from bag spouts of varying diameters.

An integral Bag-Vac dust collector creates negative pressure within the 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.

The integral flexible screw conveyor transports both free-flowing and non-free-flowing bulk materials, including products that pack, cake, smear, seize or fluidise.

The conveyor support mast cantilevers from the frame and runs parallel to the conveyor tube, allowing the castor-mounted system to manoeuvre in restricted areas.

Units are available in carbon steel with durable industrial coating or stainless steel to industrial, food, dairy or pharmaceutical standards.
