Understanding Flexicon Bulk Bag Unloader Systems
Flexicon bulk bag unloader technology centers on controlled discharge mechanisms that ensure complete material evacuation while maintaining dust containment. The core system consists of a lifting frame, spout connection assembly, and material flow activation components that work together to optimize bulk handling operations.
The SPOUT-LOCK clamp ring system forms the foundation of effective discharge control. “SPOUT-LOCK® clamp ring eliminates dust during untying, discharge, bag collapse and removal,”[4] according to Flexicon’s product development team. This sealing mechanism creates a dust-tight connection between the bulk bag spout and discharge system, preventing material loss and maintaining workplace air quality.
Material flow activation relies on pneumatically-operated FLOW-FLEXER bag activators that promote consistent discharge. “Pneumatically-actuated FLOW-FLEXER® bag activators ensure efficient material flow by compressing the bottom edges of the bag at timed intervals. This action directs contents toward the outlet spout, promoting complete and consistent evacuation of material,”[4] explain Flexicon’s design engineers.
The BFC-C model demonstrates the versatility of flexicon bulk bag unloader designs with its capacity to handle 3200 lbs[1] of bulk material. The system’s discharge rate of 135 cubic feet per hour[2] provides steady material flow for continuous production operations.
