Products Description
Need to pack bulk powders or granules into jumbo bags with high accuracy and zero dust leakage?
Guanjiang’s Bulk Bag Filling System (Sub-packaging Equipment) enables fully enclosed, automated metered packaging of bulk materials directly from your production line. Achieve ±0.3% filling accuracy for 20-200L bags, with dust-free sealed connections, ATEX compliance for explosive areas, and optional N2 protection and WIP/CIP cleaning. Ideal for chemicals, food, pharmaceuticals, and minerals.
Key Advantages of Our Bulk Bag Filling System
Precise metering system ensures consistent fill weights from 50 to 8000 kg/h, reducing product giveaway and meeting strict regulatory requirements.
Pneumatic bag-clamping device creates a fully enclosed filling environment — eliminates dust leakage, protects operator health, and keeps your facility clean.
Suitable for explosive dust/gas environments. Fully compliant with ATEX standards, with optional N₂ protection device for inert filling.
Optional Wash-in-Place (WIP) or Clean-in-Place (CIP) systems for quick changeovers between batches — meets food and pharma standards.

Frequently Asked Questions About Bulk Bag Filling
Q: How does your system handle dusty or hazardous materials without leaking?
A: Our system uses a pneumatic bag-clamping device that creates a dust-tight seal between the filling spout and the bag inlet. Combined with a dust extraction port and optional N₂ purge, it ensures zero dust escape — protecting operators and meeting strict environmental regulations.
Q: Can you fill both inner bags (sub-bags) and outer jumbo bags?
A: Yes. We offer an inner bag support device mounted on automatic connectors, plus an opening support or roll-type sealing device for inner sub-bags. This allows you to fill a disposable inner liner inside a reusable outer bag — ideal for food and pharma applications requiring high cleanliness.
Q: What is the difference between WIP and CIP cleaning for this equipment?
A: WIP (Wash-in-Place) requires some manual disassembly of specific parts before automated washing. CIP (Clean-in-Place) allows fully automated cleaning without disassembly, using spray balls to clean all internal surfaces. CIP is recommended for frequent product changeovers in food/pharma production.
Q: Can the system be integrated with my existing bulk material handling line?
A: Absolutely. Our filling system can be integrated upstream with vacuum conveyors, screw feeders, or pneumatic conveying systems, and downstream with palletizers and stretch wrappers. We provide full system integration for crushing, sieving, granulation, conveying, metering, and filling processes.
