Single-Trip Bulk Bag Unloader with Flexible Screw Conveyor
The new Single-Trip Bulk Bag Unloader allows rapid, low-cost discharging in low-headroom areas, and conveying of material at any angle to downstream processing, storage or packaging equipment. The unloader relies on the user''s forklift or plant hoist to lower single-use bulk bags onto a four-bladed bag piercing knife that cuts the bag bottom from seam-to-seam, promoting complete discharge without the use of flow promotion devices otherwise needed to move material through narrow bag spouts. Single-use bags are simply lowered onto the piercing knife, ready to discharge. Compared with reusable bags, many of which are discarded after one use, single-use bags can be less costly to purchase, and reduce the amount of material to be discarded or recycled, according to the manufacturer. The hopper, which is equipped with a hinged door to access the interior safely, charges the intake adapter of an integral flexible screw conveyor that handles free- and non-free-flowing bulk materials. The hopper is also available equipped with intake adapters and rotary airlocks for pneumatic conveying systems, as well as with universal flanged outlets for connection to the user''s downstream equipment. Construction is of stainless steel finished to industrial, food, dairy or pharmaceutical standards, or of carbon steel with durable industrial finish.
