The bag-to-hopper interface consists of a SPOUT-LOCK® clamp ring positioned atop a pneumatically actuated TELE-TUBE® telescoping tube, allowing dust-tight connections and unrestricted flow between the bag spout and hopper, as well as automatic tensioning of the bag as it empties to promote flow and evacuation. The telescoping tube raises the clamp ring assembly that seals the clean side of the bag spout to the clean side of the telescoping tube, and then lowers until the bag spout is pulled taut. Once the spout is untied, the telescoping assembly exerts continual downward tension on the spout, elongating the bag as it empties.
The discharger is also equipped with FLOW-FLEXER® bag activators that raise and lower opposite bottom edges of the bag at timed intervals, loosening compacted materials and promoting material flow into the bag discharge spout. As the bag lightens, the stroke of the bag activators increases, raising the bag into a steep "V" shape, eliminating dead spots for total evacuation of material with no manual intervention.
The transition hopper is equipped with pneumatic flow promotion devices, and a rotary airlock valve and pick-up adapter for discharging of free-flowing materials into dilute phase pneumatic conveying systems.
Full frame bulk bag dischargers offered by the Flexicon include BFF Series dischargers with bag lifting frame for forklift loading, and BFC Series dischargers with cantilevered I-beam and electric hoist and trolley for positioning of bags without the aid of a forklift.
Construction is of carbon steel with durable industrial finish, or stainless steel finished to industrial food, dairy or pharmaceutical standards.
