  • Hopper :
    The hopper is typically conical or funnel-shaped, located beneath the suspended bag to collect and direct material flow. Its smooth inner surface minimizes material buildup and promotes consistent discharge. The hopper outlet interfaces with downstream conveyors, feeders, or silos.
  • Bag Lifting System :
    To safely suspend the jumbo bag, the station includes a lifting mechanism which can be manual or motorized. Options include hoists, cranes, or forklift pockets integrated into the frame. This system securely holds the bag by its lifting loops and maintains stable positioning during the unloading process.

The working principle is simple yet highly effective:

  1. Bag Suspension :
    The jumbo bag is first lifted using the hoist, crane, or forklift and attached to the debagging station frame by its lifting loops.
