The tons bags fertilizer packing machine is a specialized piece of equipment used to quantitatively fill bulk fertilizer into large-capacity ton bags. The weight of a single bag is typically 500-2000 kg. It integrates automatic weighing, filling, bag hanging, and conveying, and is suitable for large-scale packaging of powdered or granular fertilizers such as organic fertilizers, compound fertilizers, and bio-organic fertilizers. The equipment uses a large feeding screw or gravity feeding system in conjunction with a weighing system, enabling rapid filling of large tonnage bags, reducing manual handling, and improving bagging efficiency. The tons bags fertilizer packing machine is an important piece of equipment for fertilizer companies targeting large-scale sales, exports, and warehousing turnover.
The ton bag is fitted onto the bag hanging mechanism below the filling port and secured by a pneumatic hook or bag clamping device. After the weighing system is zeroed, the feeding screw or valve opens, and material is quickly filled into the ton bag. The weighing sensor monitors the weight inside the bag in real time, automatically switching to slow feeding when the weight approaches the target value, and stopping after precise replenishment. After filling, the bag-hanging mechanism releases, and the ton bag is moved out of the packaging position by the conveyor, awaiting forklift or overhead crane transport. The entire process is controlled by a PLC, which can set target weight, feeding speed parameters, and record packaging batch data.
Feeding Mechanism: Employs a large-diameter screw feeder or pneumatic slide valve, with two-stage feeding (fast and slow) to ensure both high flow rate and accuracy.
Weighing System: Four load cells support the weighing platform or bag-hanging frame, monitoring the weight of the ton bag and material in real time.
Bag Hanging and Clamping Device: Pneumatic hooks or clamping arms fix the ton bag opening below the filling port, ensuring stability during filling.
Filling Port and Dust Collection Interface: The filling port is height-adjustable or retractable to accommodate different bag heights, and is equipped with a dust collection pipe to reduce dust.
Conveying and Lifting Connection: A roller conveyor or pallet conveyor can be installed at the bottom for easy forklift and overhead crane operation.
Frame and Platform: Heavy-duty steel frame. The frame supports the feeding and weighing components and includes an operating platform and guardrails.
Large Packaging Weight: Single bag can be filled from 0.5 to 2 tons, suitable for bulk sales and logistics transportation.
Accurate Measurement: Four-sensor weighing, accuracy up to ±0.2%, meeting trade settlement requirements.
Fast Filling Speed: Large feeding capacity design, capable of filling hundreds of kilograms per minute.
Good Dust Control: Sealed filling port and ton bag opening, equipped with a dust removal interface to reduce on-site dust.
High Automation: Fully automatic bag hanging, filling, metering, and bag loosening; can be integrated into the production line control system.
Robust Structure: The frame and weighing platform are designed for heavy loads, suitable for long-term continuous operation.
