This new mobile frame-mounted bulk bag discharger with flexible screw conveyor allows rapid, dust-free discharging and conveying of bulk solid materials at multiple plant locations. Warehouse Conveyor Equipment
The Bulk-Out BFF Series discharger allows forklift-loading of bulk bags from 36 to 84 in. tall. A removable bag-lifting cradle with Z-Clip strap holders permits bulk bags to be attached securely at floor level from an ergonomic standing height, and then forklifted into cradle cups atop the discharger's upright posts.
The bag spout is pulled through a 12-in.-diam iris valve which is then closed around the spout, preventing material flow. The spout can then be untied, the snap-action access door closed, and the valve released slowly, allowing controlled flow into the enclosed hopper through the bulk bag interface chute.
Complete discharge is aided by Flow-Flexer bag activators that press against opposite bottom sides of the bag at timed intervals to form a steep "V" shape, and top-mounted Pop-Top extension devices that raise the uprights as the bulk bag empties, promoting the flow of material from the corners of the bag through the bag spout.
The hopper is vented to a Bag-Vac dust collector that creates negative pressure within the sealed system to contain displaced air and dust, and vacuum any particles trapped in bag creases during disconnect. Reverse-pulse air jets on a timed cycle dislodge material accumulated on the filters, returning it to the material stream.
The enclosed 5.5-cu-ft hopper measures 30 in. square by 42 in. high and is equipped with proximity level sensors, and a pneumatic vibrator assembly to promote flow of material to the conveyor.
The outlet of the hopper charges the inlet of a Bev-Con flexible screw conveyor that propels free- and non-free-flowing bulk materials at a 45 degree incline in user-specified distances for discharging directly into processing equipment or storage vessels through 10-in.-diam downspouting.
Specialized geometry of the internal screw allows handling of materials that pack, cake, smear, seize, or fluidize, with no separation of blends. The screw is the only moving part contacting material, and is driven beyond the point of discharge, preventing material contact with seals or bearings, and allowing rapid cleaning.
Mounted on a mobile base with support mast, the self-contained unit can be rolled to feed various locations or 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, with stainless steel material contact surfaces, or in all-stainless steel finished to industrial, food, dairy, or pharmaceutical standards. Its NEMA 4 control panel with PLC allows manual and automatic start/stop and speed adjustment.
