Mobile Bulk Bag Discharger/Flexible Screw Conveyor, Hopper

Powder Bulk Solids Staff | Jul 27, 2021

This new Flexicon mobile bulk bag discharger with mobile flexible screw conveyor allows dust-free discharging of bulk solid materials and conveying to downstream process equipment or storage vessels throughout the plant.

Mounted on locking casters, the Bulk-Out BFF Series discharger has four adjustable extension posts to accommodate bulk bags 36-84 in. tall. The removable bag-lifting frame with Z-Clip strap holders allows bulk bags to be attached at ground level, then forklifted into receiving cups on the discharger frame.

A Spout-Lock clamp ring atop a pneumatically-actuated Tele-Tube telescoping tube secures the clean side of bag spout to the clean side of the equipment and exerts continuous downward tension on the bag as it empties and elongates, promoting flow and evacuation. A vent port with filter sock contains dust.

Additional flow is afforded by Flow-Flexer bag activators that raise and lower opposite bottom sides of the bag at timed intervals into a steep “V” shape, and top-mounted Pop-Top extension devices that elongate the entire bag, promoting total discharge with no manual intervention.

The discharge housing of the mobile flexible screw conveyor is supported by a mast affixed to the mobile discharger frame, allowing the transfer of free- and non-free-flowing bulk materials to multiple destinations.

The flexible screw is the only moving part contacting material and is driven by an electric motor beyond the point at which material is discharged, preventing material contact with seals.

The entire unit can be rolled to a cleaning station. A lower clean-out cap on the conveyor tube can be removed to flush the smooth interior surfaces with steam, water or cleaning solutions, or to fully remove the flexible screw for cleaning and inspection.

The system is available in carbon steel with durable industrial coating and stainless steel material contact surfaces (shown) or in all-stainless steel finished to industrial, food, dairy, or pharmaceutical standards.
