Bulk-Bag Weighing & Suspension System | Milk Powder Case Study
.
The Challenge: Precision and Dust Control in Dairy Powder Filling
In high-volume milk powder production, manual filling often leads to inconsistent bag weights and significant product waste. Our client needed a solution to automate the filling of 900kg bulk bags while ensuring high accuracy and seamless integration with existing upstream equipment.

The Solution: Integrated Suspension Weighing Station
We supplied a custom Bulk-Bag weighing station featuring a robust metal suspension frame. Key technical components include:
We supplied a custom Bulk-Bag weighing station featuring a robust metal suspension frame. Key technical components include:
- Precision Load Monitoring: The bag is suspended from four 500kg stainless steel load cells, providing a total capacity of 2,000kg with high-resolution accuracy.
- Integrated Feeding System: A heavy-duty auger and vibrating screen (sieve) ensure a consistent material flow while removing any oversized particles.
- Automated Control Loop: The system utilizes a digital dosage controller where the operator sets a target (e.g., 900kg). Upon reaching the setpoint, an automatic butterfly valve closes instantly, simultaneously halting the auger and sieve to prevent overfilling.
.
The Result: Improved Throughput and Reduced Material Loss
The automated cutoff eliminates human error in weight measurement, ensuring every bag meets strict trade-to-weight standards.

- Enhanced Safety: The suspension frame allows for easy forklift access, enabling operators to remove pallets quickly and safely once the cycle is complete.
- Process Efficiency: By combining sieving, feeding, and weighing into one automated step, the plant increased its hourly “Big-Bag” output while maintaining a dust-free environment.
