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.
Dust collection options include a dust plenum consisting of a hollow hopper rim vented to a plant dust collection system, as well as a wide-diameter gasket at the rim of the hopper, which forms a seal against the bottom of the bulk bag while it is being lowered onto the blade assembly. 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.
Also offered are transitions for other mechanical or pneumatic conveying systems, or universal flanged outlets for connection to downstream processes.
