NPK Fertilizer Production Line with Adjustable NPK Ratios, High Granulation Rate, and Modular Configuration for Granular Compound Fertilizer
This complete NPK compound fertilizer production line is specially developed for producing granular compound fertilizer with adjustable nitrogen-phosphorus-potassium ratios. It covers the full-process workflow from automatic batching to finished-product packaging.
Finished NPK fertilizer granules feature uniform particle size, high mechanical strength, and good anti-caking performance, making them convenient for storage, transportation, and farm application. This turn-key solution is widely adopted by medium to large fertilizer factories for producing different-formula compound fertilizers.
- Flexible formula adjustment supporting various NPK proportion formulas for different crop demands
- Two optional granulation technologies: wet drum granulation or dry double-roller extrusion granulation
- High granulation rate, stable continuous running, low failure rate, and easy maintenance
- Modular configuration with customizable whole-line layout according to customer workshop and site conditions
- High automation level reducing manual operation with return material recycling system improving raw-material utilization
- Finished round granules with high strength, resistant to breakage and anti-caking for long-term storage
- Raw material automatic batching
- Crushing
- Mixing homogenization
- Granulation
- Drying
- Cooling
- Rotary screening
- Finished-product packaging
Unqualified oversized & fine powder returns back for re-granulation to realize material recycling.
