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 percent, compared with connecting reusable bags to conventional unloaders, according to the company.
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.
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.
Also offered are transitions for other mechanical or pneumatic conveying systems, or universal flanged outlets for connection to downstream processes.
Bag piercing hopper of BULK-OUT® discharger slices bag bottom from seam to seam, reducing labor and discharging cycle times by up to 95 percent per bag.
