The terminal packaging stage is often the biggest bottleneck in fertilizer factories, causing severe product backlogs and high labor overheads. Our heavy-duty Full Automatic Weighing and Bagging Fertilizer Granulator Line is engineered to eliminate this operational delay completely. This high-throughput automatic packaging fertilizer line seamlessly links advanced double-roller dry compaction machinery with a high-speed bagging machine 25kg 50kg setup. Managed by a unified digital control terminal, the entire final packaging line executes precise real-time weighing, filling, stitching, and sealing with absolute minimal human labor, helping your business accelerate warehouse distribution and maximize shipping efficiency.

• High-Speed Gravimetric Packaging: The integrated automatic packaging fertilizer line features advanced load cells that deliver high-precision filling accuracy within plus or minus 0.2% for continuous high-speed shipments.
• End-to-End Smart Automation: Eliminates manual bagging delays by automatically executing bag clamping, precise product filling, optical-sensor tracking, and automated heavy-duty sewing.
• Moisture-Proof Heavy Industrial Sealing: The terminal bagging machine 25kg 50kg is equipped with premium folding or heating-sealing heads to guarantee robust, leak-proof commercial packaging for marine export.
• High-Density Roller Dry Compaction: The front-end processing unit utilizes premium room-temperature dry mechanical squeezing, outputting robust fertilizer particles that are immediately ready for bulk packing.

• Production Capacity: 3 - 10 Tons/Hour (Configured for automated mass wholesale packaging)
• Bagging Range Options: Adjustable from 20kg to 50kg per bag (Customizable for bulk jumbo bags)
• Packaging Output Velocity: 300 to 450 bags per hour (Based on material flow and bag dimensions)
• Primary Granulation Core: Heavy-Duty Double Roller Dry Extrusion Compactor Line
• Terminal Operation Interface: Centrally linked PLC monitor desk featuring real-time bagging count memory

This high-performance final packaging line runs on a continuous, fully synchronized mechanical framework:

1. Bulk Ingredient Digital Batching: Raw chemical powders and nutrient mineral crystals are systematically weighed and gathered via automated belt scales to maintain precise chemical formula specifications.
2. Intensive Continuous Dry Blending: The bulk ingredients are fed into a heavy-duty continuous ribbon mixer, utilizing aggressive mechanical agitation to create a completely uniform matrix before the pressing stage.
3. Driven Pre-Density Forced Feeding: The mixed dry powder drops into a vertical feed screw throat, which pre-compresses and de-aerates loose material to prevent air pockets during the roller squeeze.
4. Hydraulic Double-Roller Compactor: The powder passes between two high-precision counter-rotating rollers. Under immense hydraulic squeezing forces, the loose dry mix is instantly flattened into hard, dense flakes without adding moisture.
5. Integrated Flake Breaking & Sifting: The solid compressed sheets drop directly into an enclosed breaking mill to crack the flakes into raw fragments. The fragments then enter a rotary screening machine to extract standard commercial granules (2-4mm), while off-size dust is automatically returned for re-compaction.
6. Constant-Flow Terminal Material Surge: Qualified graded fertilizer granules flow continuously into an overhead storage surge hopper equipped with level-monitoring sensors to feed the automated packaging system steadily.
7. Precision Gravimetric Bagging & Filling: The granules drop into the bagging machine 25kg 50kg station. The pneumatic system secures the bag, executes a dual-speed gravimetric fill (fast feed for volume, slow feed for accuracy), and releases the filled bag onto a conveyor.
8. Automated Conveying & Heavy Stitch Sealing: The filled commercial bags are moved along an automatic alignment conveyor straight through a heavy-duty industrial sewing or heat-sealing unit, creating a perfect weatherproof finish ready for direct truck loading or container storage.
