Big Bag Filling Machine
Industrial-Grade Ton Bag Filling System for Bulk Materials
Big Bag Filling Machine Overview
Our Big Bag Filling Machine (also called Ton Bag Filling System) is a professional bulk packaging solution designed for large-scale filling of granular and powdery materials. It efficiently loads materials (200–2000 kg per bag) into flexible intermediate bulk containers (FIBCs/ton bags), supporting both granular material filling (biomass pellets, mineral granules) and powder filling (chemical powder, cement powder). With a filling speed of 5–25 bags/hour and weighing accuracy of ±0.5–1%, it meets industrial bulk packaging needs—ideal for biomass energy, chemical, mineral processing, and agricultural sectors.

Core Components of Big Bag Filling Machine
The stable bulk filling performance relies on 5 specialized components, optimized for heavy-load and dust-free operation:
Features a high-load pneumatic hoist that lifts empty ton bags (200–2000 kg capacity) to the filling port. Adjustable clamping jaws secure the bag mouth tightly, preventing material leakage and ensuring stable filling without bag slipping.
- Granule Feeding: Variable-speed screw feeder with anti-breakage design, ensuring uniform flow for large-particle materials (e.g., biomass pellets).
- Powder Feeding: Auger feeder + fluidization device, eliminating powder bridging and ensuring smooth filling for fine materials (e.g., cement powder).
Equipped with a load cell (precision class C2) and dynamic compensation algorithm. It adjusts feeding speed in three stages (fast, medium, slow) to maintain accuracy within ±0.5–1%, even for high-volume bulk materials.
PLC system with touch screen supports parameter setting (bag weight, filling speed, feeding mode) and real-time data monitoring (filled quantity, error rate). It stores 15+ sets of parameters for quick switching between materials, reducing downtime.
Working Principle of Big Bag Filling Machine
- Ton Bag Preparation: Operators hang empty ton bags on the lifting mechanism, and the pneumatic hoist lifts them to the filling port.
- Bag Clamping & Sealing: Clamping jaws secure the bag mouth to the sealed filling hood, preventing dust leakage and material spillage.
- Parameter Selection: Select material type (granule/powder) and target weight via the touch screen, calling pre-stored parameter sets (e.g., 1000kg/bag for biomass pellets).
- Staged Filling: The feeder starts in fast mode (fills 80% of target weight), switches to medium (95%), then slow (100%) to avoid overweighing.
- Weighing & Calibration: The load cell monitors weight in real time, stopping feeding automatically when reaching the target. Dynamic compensation corrects for material flow fluctuations.
- Unloading & Sealing: Clamping jaws release, and the hoist lowers the filled ton bag for manual or automatic sealing (sewing or heat sealing). The dust collector continues running to capture residual dust.
Core Advantages and Features
Why Choose Us Big Bag Filling Machine？
Fills 200–2000 kg per bag at 5–25 bags/hour, 5–8x faster than manual filling. A 15 bags/hour model replaces 4–6 workers, cutting labor costs by $30,000–$50,000 annually.
Switches between granular material filling and powder filling without core component replacement, adapting to diverse bulk materials and reducing equipment investment.
C2-class load cell + three-stage feeding control ensures accuracy of ±0.5–1%, meeting industrial packaging standards and avoiding material waste.
Heavy-duty steel frame and industrial-grade components (pneumatic hoist, load cell) support 24/7 continuous operation. With regular maintenance, service life reaches 8–12 years.
Wet fertilizer? Add anti-stick Teflon auger. Explosive metal powder? Use ATEX Certified Big Bag Packer. Fragile seeds? Swap to soft rubber belt.

FAQ about Big Bag Filling Machine
It is an automated device specifically designed to accurately fill bulk solid materials (such as powders, granules, and small lumps) into FIBCs (Flexible Intermediate Bulk Containers). Typical bag weights range from 500-2500 kg and are widely used in the chemical, building materials, and agricultural industries.
It is suitable for most solid materials, including powders (cement, flour, chemical powders), granules (fertilizer, plastic granules, seeds), and small lumps (ore pellets, feed pellets). However, hygroscopic, highly corrosive, or high-temperature materials require a custom-built machine.
The standard machine supports 500-2500kg per bag, which is the mainstream size for industrial ton bags. If you require smaller weights (e.g., 200kg) or larger weights (e.g., 3000kg), please contact us to customize the appropriate weighing system and bag hanging mechanism.
We support common PP woven FIBC bags, moisture-proof FIBC bags with PE linings, and breathable FIBC bags (to prevent bulging). We also support special FIBC bags, such as anti-static FIBC bags (for chemical explosion-proof applications) and food-grade FIBC bags (for grain and milk powder packaging). Please confirm in advance that the bag opening size matches the machine’s filling port.
The speed depends on the machine model (semi-automatic/fully automatic), material flowability, and bag weight. The typical range is 5-30 bags/hour. For example, a fully automatic machine can fill 1000kg of granular materials at 20-25 bags/hour. Powders require slow filling and precise control, so the speed is slightly lower (8-15 bags/hour).
Semi-automatic machines require manual bag hanging and unloading, with only filling and weighing automated. They are suitable for small production runs (<10 bags/hour). Fully automatic machines use robotic arms/conveyors to automatically complete bag hanging, filling, unloading, and conveying, eliminating manual intervention. They are suitable for large production runs (>15 bags/hour), but are more expensive.
The typical accuracy is ±0.1%-0.5% (e.g., ±1-5kg for a 1000kg bag). This relies on high-precision weighing sensors. If the material is dusty or has poor flowability, the “fast fill + slow fill” dual-stage control can further improve accuracy.
The machine has built-in dust-proof features: ① The filling port is sealed against the bag opening to prevent dust leakage; ② It is equipped with a dust collector (such as a bag filter) to remove dust generated during filling. Some models can also be equipped with a negative pressure system for high-dust materials (such as cement and lime powder).
Buyer's Guide
How to Choose the Best Big Bag Filling Machine？
Calculate daily bulk packaging volume and select a model with 10–20% redundancy (e.g., 80 bags/day needs a 12 bags/hour machine).
Inform the manufacturer of material type (granule/powder), particle size/mesh, moisture content, and abrasiveness—ensure the feeder and lining are suitable.
Choose C2-class load cells for high-precision needs (chemicals, export products); standard precision works for general bulk materials.
For powder materials or eco-strict regions, select models with pulse dust collectors (emissions ≤5mg/m³) to avoid environmental fines.
Small workshops can use basic PLC models; large lines benefit from IoT-connected systems (remote monitoring, data logs, fault alerts).
