Discharger Cuts Cycle Times

The BULK-OUT Bulk Bag Discharger features a bag piercing receiving hopper and side-mounted flow promotion devices to feed downstream processes at ultra-high rates.

The BFC Series discharger features a cantilevered I-beam with electric hoist and trolley for loading a bulk bag without the use of a forklift, and lowering it onto the hopper's four-bladed knife. For applications that are suitable for single use bags, piercing the bag bottom from seam to seam reduces labor and cycle times by up to 95%, compared with connecting reusable bags to conventional unloaders, according to the company. 

Pneumatically-actuated FLOW-FLEXER bag activators press and release opposite sides of the bag at timed intervals, promoting rapid and complete evacuation of free- and non-free-flowing materials.

The periphery of the bag bottom self-seals against a wide-diameter gasket at the rim of the hopper, eliminating the cost and additional headroom required for bag spout interfaces of conventional unloaders.

An optional dust plenum consisting of a hollow hopper rim vented to a plant dust collection system provides a secondary dust containment measure.

Compared with reusable bags, many of which are discarded after one use, single-use bags are typically less costly to purchase, and contain less material to be discarded or recycled.

The hopper transition charges an optional flexible screw conveyor that transfers free- and non-free-flowing bulk materials from large pellets to sub-micron powders, including products that pack, cake, seize, smear, fluidize or break apart, with no separation of blends.
