Automatic Bagging and Palletizing System for Compound Fertilizer Packaging
The fertilizer packaging sector handles large volumes of granular and powder materials and requires equipment that can manage steady flow, fast bag changes, and reliable sealing. Production lines must remain stable even under high throughput, while also adapting to different bag sizes, stacking patterns, and product weights.
- Product name (Material): Compound fertilizer
- Bag material: Outer woven bag with inner PE liner
- Bag style: Single-fold open-mouth bag
- What we provided: Servo dual-scale system, automatic open-mouth bagging machine, high-speed bag sewing machine, ABB robotic palletizing system
A compound-fertilizer producer implemented our automatic bagging and palletizing solution to support fast, continuous packaging across multiple weight specifications. The project involved a complete line designed to handle conveying, dosing, bag placing, filling, sealing, palletizing, and automated line transitions.
Project Requirements
The packaging system needed to deliver a line capacity of at least 800 bags per hour while supporting three weight formats: 25 kg, 40 kg, and 50 kg. The packaging material consisted of woven bags with an inner PE liner, using a single-fold open-mouth structure. The line also required accurate rejection of non-conforming bags and quick switching between bag types to suit different production runs.
Our Solution
Detai supplied a full combination of servo weighing units, a fully automatic open-mouth bagging machine, a high-speed sewing system, and an ABB robotic palletizer. The system included vacuum-based bag detection, automatic bag rejection, and servo-driven one-touch adjustments to support smooth changeovers. These features ensured stable speed and consistent filling accuracy throughout the operation.
Key components in the line were designed for durability and hygienic handling. Critical contact areas were built from 304 stainless steel, while the conveyor belts used high-quality PVC materials suitable for fertilizer applications. The robotic gripper was made from high-strength aluminum alloy to maintain stability during high-speed stacking. All electrical and pneumatic components followed the customer’s designated brand requirements, including Siemens, Mettler Toledo, FESTO, and ABB, ensuring seamless integration with the customer’s existing systems.
This complete solution delivered high output, accurate filling, reliable sealing, and stable palletizing performance, meeting the customer’s expectations for efficiency, adaptability, and long-term operational reliability.
