Bulk Bag Unloader
Product Overview
The ZD-D Series Bulk Bag Unloader provides a clean and efficient solution for discharging FIBC (big bag) contents. The system features a sealed discharge hood that connects directly to downstream equipment — preventing dust escape. Pneumatic massagers help difficult materials flow freely, while the integrated hoist and trolley make bag changeover quick and safe.
Key Advantages
- Dust-Controlled: Sealed discharge hood with dust extraction port
- Heavy-Duty Frame: Robust carbon steel or SS304 construction
- Flow Assistance: Pneumatic massage paddles for sticky or bridging materials
- Quick Bag Change: Electric hoist with trolley on I-beam for fast bag swap
- Integrated Design: Direct connection to screw feeder, conveyor, or mixer
- Safe Operation: Safety interlock on discharge gate; bag liner tensioner
- Optional Weighing: Load cells for batch weighing and inventory tracking
