Bulk Bag Unloader

The bulk bag unloader (emptying station/ feeding station of bulk bags) is an automated equipment designed for efficient, safe, and dust-free unpacking of big bags containing 200-2000kg materials. Compared with the equipment, traditional manual unpacking features low efficiency, dust pollution, and safety hazards.

Working Principles

The bulk bag is hoisted and secured onto the support frame via a lifting device. After the bag spout is opened or the bag is cut, the material falls into the equipment by gravity. It is then processed by an anti-bridging device to prevent agglomeration and a screening device to remove impurities, before being conveyed to downstream equipment via a screw or pneumatic conveyor. Simultaneously, a negative-pressure dust collection system captures airborne dust to prevent dispersion, enabling efficient and dust-free unloading of bulk bag materials.

Product Advantages
  • Efficiency Improvement
    Semi-automated operation reduces manual intervention and increases the speed of unpacking by 30%-50%.
  • Safety Compliance
    The design of double anti-drop hooks, emergency stop button, etc. complies with GB/T 3811-2008 and EN 954-1:2006 standards.
  • Environmental Compliance
    Pulse blowback system for dust removal with filtration accuracy ≤0.3μm and dust emission ≤10mg/m³; can be connected with central dust collection system.
  • Flexible Adaptation
    Compatible with PE/PP and other packaging materials; adjustment can be made through PLC parameter setting; suitable for materials with poor fluidity.
Applicable Fields
