Big bag filling machine with modular design for weighing and filling of big bags (FIBCs) with powders, granules or other free-flowing materials

• Designed for high-precision filling of 100–1000kg bulk bags, ideal for industries with strict hygiene and process control requirements
• Integrated weighing module within the machine frame ensures stable load-cell accuracy by eliminating interference from floor vibrations
• High-precision electronic weighing system with a measurement error of less than ±0.2%, meeting demanding process specifications
• Multiple feeding configurations available such as screw feeder, rotary valve, butterfly valve, positioning valve, vibrating chute, or pipe feeding, making the filling system adaptable to different material properties
• Strong modular compatibility: can be integrated with conveying, crushing, screening, dust collection, and metal detection systems to form a complete production line
• Compact, space-efficient structure suitable for cleanroom environments and automated production setups
• Dust-free filling design maintains a clean working area, compliant with GMP and FDA hygiene standards
• Extensive customization capabilities to accommodate various industries, bag types, and process integration needs

• Weighing range
  Adjustable from 100kg to 1000kg to suit different FIBC bag sizes and production capacities
• Accuracy
  Standard precision of ±0.2%; optional high-precision version of ±0.1%, suitable for high-value materials such as lithium battery powders
• Feeding options
  Available with screw feeder, rotary valve, butterfly valve, vibration chute, or pipe feeding, selected according to material characteristics
• Anti-clogging design
  Equipped with pneumatic arch breaker or mechanical agitator to prevent bridging and ensure stable flow, especially for cohesive materials
• Dust control system
  Pulse-jet dust collector for high-dust environments (chemical or construction materials) or negative-pressure sealed suction system for pharmaceutical and food-grade applications
• Bag compatibility
  Compatible with round, square, antistatic, and food-grade FIBCs
• Bag handling options
  Manual bag hanging (economic version) or automated clamping and robotic bag handling (for full automation lines)
• Filling nozzle design
  Standard filling spout for general applications or telescopic filling nozzle to minimize dust emission

For powder processing, we also provide a .
