| Our engineering team assesses flowability, density, and particle size. We recommend a screw feeder and screw conveyor for powders, gravity feed for free-flowing granules, and tubular drag conveyor for fragile materials. |
Most applications take 30–90 seconds per bag. The final cycle time depends on the material type, feed rate, and required final weight accuracy. (Starts with the time frame)
Options include:
It typically uses a support frame, inflatable neck seal, weighing system, and automatic material feed (screw feeder, screw conveyor etc.) to fill a bag to the required weight.
Most fillers handle standard 500–2000 kg bulk bags, but some machines can be adjusted for custom bag sizes.
Densification is the process of settling material inside the bag during filling using a vibrating deck or bag massagers. This compacts the material, removes trapped air, and ensures the bag achieves maximum stability, making it safe and easy to stack for transport.
Accuracy is primarily ensured by using a gravimetric (weighing) system that incorporates high-precision load cells integrated into the bag support frame. This allows the PLC to monitor material weight in real-time, shutting off the feeder precisely when the target weight is reached, resulting in ±0.25% - 0.5% accuracy.
A bulk bag filler is a heavy-duty industrial system used to automatically load powders, granules, or flakes into Flexible Intermediate Bulk Containers (FIBCs). The material is metered into the bag through a fill head, while the bag is typically densified using vibration to ensure a stable, flat-topped load.
