The discharger portion of the skid-mounted system includes a cantilevered I-beam with electric hoist and trolley to lift and position bulk bags without the use of a forklift. A SPOUT-LOCK® clamp ring forms a high-integrity seal between the clean side of the bag spout and the clean side of the equipment, while a TELE-TUBE® telescoping tube maintains constant downward pressure on the clamp ring and bag spout, elongating the bag as it empties to promote complete discharge.
Material flow is aided by FLOW-FLEXER® bag activators that raise and lower opposite bottom sides of the bag in timed intervals.
A BAG-VAC® dust collector integral to the dust-tight system creates negative pressure to collapse empty bags prior to retying and disconnection, eliminating dust emitted during manual flattening of empty bags.
The unloaders’ surge hopper is equipped with a high capacity rotary airlock valve to feed material into a pneumatic conveying line leading from a positive displacement blower at high rates.
