Above the connection point is a "Power-Cincher" pneumatically actuated flow-control valve that cinches the bag spout concentrically, allowing retying of partially empty bags with no dusting. The unloader 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.
The surge hopper discharges into a low-profile &lumping device with dual rotors and three-point heads to break up agglomerates that have formed in the bag. On-size material is discharged into a gravimetric feeder connected by PLC to a scale on the plant floor, ensuring the loading of accurate batch weights into rigid totes placed on the scale.
