Full Auto PLC Control High Granulation Rate Fertilizer Granulator Line for Automatic Weighing and Bagging

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.
