A Flexicon bulk bag discharging system with integral pneumatic conveying system transfers material from bulk bags to silos and other storage vessels. Unlike most discharging systems that move material from bulk bags to smaller storage vessels and process equipment, this positive pressure pneumatic system is designed to fill bulk storage facilities on islands or other locations unable to receive large volumes of bulk material by rail or bulk truck.
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 unloader's 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.
The company also manufactures bulk bag dischargers as stand-alone units or systems integrated with mechanical or pneumatic conveying systems, weigh batching controls, bulk bag conditioners and other equipment, as well as bulk bag fillers, bag dump stations, box/container/drum tippers, drum fillers, weigh batching and blending systems, and engineered plant-wide bulk handling systems with automated controls.
