The Bulk-Out bulk bag discharger from Brisbane bulk handling manufacturer Flexicon 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 that loads a bulk bag without the use of a forklift and lowers it onto the hopper’s four-bladed knife. For applications that are suitable for single-use bags, piercing the bottom of a bag from seam to seam reduces labour and cycle times by up to 95 per cent, compared with connecting reusable bags to conventional unloaders.
Pneumatically-actuated Flow-Flexer bag activators press and release opposite sides of the bag at timed intervals, promoting rapid and complete evacuation of free-flowing and non-free-flowing materials.
The periphery of the bag’s bottom seals itself against a wide-diameter gasket at the rim of the hopper, eliminating the additional headroom and cost 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 actually discarded after one use, single-use bags are typically cheaper to purchase and contain less material to be discarded or recycled.
The hopper transition charges an optional flexible screw conveyor that transfers free-flowing and non-free-flowing bulk materials from ranging in size from large pellets to sub-micron powders, including products that pack, cake, seize, smear, fluidise or break apart, with no separation of blends.
Transitions for other mechanical or pneumatic conveying systems, or universal flanged outlets for connection to downstream processes are also available.
