Project Scope: Fertilizer production line equipment, process design and plant engineering services. Finished fertilizer products are not supplied.



Different NPK formulations require different granulation processes. SYM designs fertilizer granulation plants around your raw material properties, target capacity, finished granule size, available utilities and investment plan.
Compare the three main solutions below to select the right granulation process for your NPK fertilizer production line.
Not Sure Which Granulation Process Fits Your Project?
Send us your raw materials, target formula and required capacity. Our engineers will recommend a suitable production process and preliminary equipment configuration.
Small to Medium NPK Fertilizer Plant (10,000–50,000 tons/year)
Designed for regional fertilizer manufacturers and new plant investors, this compact NPK production line can be configured with batching, mixing, granulation, screening and packaging modules according to the raw materials and required capacity.
Large Scale NPK Compound Fertilizer Turnkey Plant (100,000–500,000 tons/year)
Designed for industrial fertilizer manufacturers requiring continuous high-output production, this turnkey NPK fertilizer manufacturing plant integrates automated batching, granulation, drying, cooling, screening, coating, packaging and centralized process control.
Regional Customization Highlights:
Southeast Asia / South America: Corrosion-resistant and moisture-proof configurations designed for humid operating environments and varying raw material conditions.
Middle East: Heat-resistant and dust-proof configurations, compatible with sulfur-based or nitrate-based NPK compound fertilizer processes.
Africa: Electrical systems adapted for voltage fluctuations, with durable structures and simplified maintenance.


Our compound fertilizer production line follows a streamlined, efficient workflow:
1. Precision Batching
The required raw materials are accurately proportioned according to the target NPK formula, helping maintain consistent nutrient ratios and stable production.
2. Homogeneous Mixing
A dual-shaft paddle mixer achieves thorough 3D blending (CV ≤ 5%), creating ideal conditions for uniform granulation.
3. Efficient Granulation
A large rotary drum granulator forms high-strength particles via liquid-phase binding or additives. Alternative processes like double roller dry granulation or disc granulation are available based on material properties.
4. Intelligent Drying
The rotary dryer, with adjustable concurrent/counter-current airflow and optimized lifting flights, stabilizes moisture content at ≤2.0%, enhancing particle physical strength.
5. Uniform Cooling
A rotary cooler brings hot granules to near ambient temperature, preventing caking and fixing particle structure.
6. Precise Screening
Multi-layer vibrating screens separate finished granules (2–4 mm / 3–5 mm). Oversize and undersize materials are automatically crushed and recycled, achieving a raw material utilization rate >98%.
7. Finished Product Coating
Equipped with a rotary coating machine, the finished fertilizer undergoes functional treatments such as anti-caking, moisture resistance, or controlled-release coating, effectively enhancing product added value and market competitiveness.
8. Automatic Packaging & Palletizing
High-speed bagging scales (±0.2% accuracy) and optional robotic palletizers handle the final steps from production to warehouse.
A complete NPK fertilizer manufacturing plant consists of the equipment listed below. The equipment can be supplied as an integrated turnkey fertilizer processing plant or individually for capacity expansion and production line upgrades.
| Process Stage | Key Recommended Equipment | Features | Independent Supply & Service |
| Pre-processing | Chain Crusher, Urea Vertical Crusher | Handles high-moisture, hard, or caking materials. High processing capacity with easy maintenance. | Available for standalone purchase. Wear parts kits (e.g., blades, screens) provided. |
| Mixing & Granulation | Dual-Shaft Mixer, Rotary Drum Granulator | High mixing homogeneity. Granulator achieves ≥85% pelletizing rate, stable operation, with wear & corrosion-resistant drum. | Offers retrofit services for existing machines (e.g., drum replacement, drive upgrades). |
| Drying & Cooling | Rotary Dryer, Rotary Cooler | High thermal efficiency, compatible with various heat sources. Cooler provides rapid heat dissipation and robust construction. | Configurable as separate units. Supply replacement parts like optimized lifting flights and bearing assemblies. |
| Screening & Coating | Multi-Layer Linear Vibrating Screen, Rotary Coating Drum | High screening precision and large capacity. Ensures even coating application for various functional treatments. | Available for individual procurement. Supplies key components such as screen meshes and coating liquid atomization systems. |
| Dust & Emission Control | Pulse Bag Dust Collector, Exhaust Scrubber | Dust removal efficiency >99.5%. Features automatic cleaning and corrosion-resistant materials, meeting stringent emission standards. | Sold as standalone environmental units. Provides consumables like filter bags, solenoid valves, and spray nozzles. |
| Control System | PLC Central Control System | Enables centralized monitoring, data traceability, and remote diagnostics to enhance management efficiency. | Offers automation upgrade services for existing production lines. |
A typical line includes: raw material batching system, dual-shaft mixer, granulator (rotary drum / double roller / disc), dryer, cooler, screening system, recycle crushing system, coater (optional), automatic packaging & palletizing system, along with conveying, dust removal, and electrical control systems.
Our equipment features a modular design but is custom-configured based on your raw material properties, required capacity, site layout, and local standards to ensure long-term, stable performance.
The batching and control system can be configured for multiple NPK formulations. The available formula range depends on the selected granulation process and raw material characteristics.
The cost depends on the required capacity, selected granulation process, automation level and scope of supply. Send us your basic project requirements to receive a recommended equipment configuration and preliminary budget.
Every NPK compound fertilizer project has different production requirements, so the final plant cost depends on the selected process and overall equipment configuration.
Send us your raw materials or target NPK formula, required capacity, desired granule size and project country. Our engineers will recommend a suitable granulation process and provide a preliminary equipment configuration and project budget.
