Transforming Fertilizer Performance with a Slow-Release Coating Production Line
In modern agriculture, slow-release fertilizers (also known as controlled-release fertilizers) are becoming essential for improving nutrient efficiency, reducing application frequency, and minimizing environmental loss. To meet the growing demand for high-performance fertilizers, we provide a complete slow-release fertilizer granule coating production line, engineered for precision, reliability, and scalability.
We specialize in manufacturing fertilizer surface treatment and coating equipment, including rotary coating machines, automatic dosing systems, and anti-blocking conveyors, helping fertilizer producers upgrade their products with slow-release technology.
Project Example: 5 tons/hour slow-release fertilizer coating line for a urea plant
Products: Polymer-coated urea (PCU) and sulfur-coated urea (SCU)
Capacity: 5 tons/hour
Delivered Equipment:
Rotary fertilizer coating machine (5 tons/hour, anti-corrosion lining)
Coating material melt-mixing tank
High-precision spray system
Automatic feed conveyor with anti-stick design
Dust and odor removal control device
PLC control cabinet with temperature monitoring
Key Benefits of Slow-Release Fertilizer Coating Lines
✔ Increased fertilizer utilization rate (30–50% improvement)
✔ Reduced nitrogen leaching and volatilization
✔ Improved crop yield and soil health
✔ Extended nutrient release period (30–90 days)
✔ Enhanced product appearance and flowability
✔ Meets global standards for controlled-release fertilizers
What Is a Fertilizer Coating Production Line?
A fertilizer coating production line is a post-treatment system installed after the granulation and drying process. Its purpose is to apply a protective or reactive liquid layer onto the surface of fertilizer granules (such as urea, NPK, or ammonium sulfate) to:
Control nutrient release rate
Prevent caking during storage
Improve water resistance
Add micronutrients or bio-stimulants
(表格)
Application Scenarios
Urea coating lines for polymer-coated or sulfur-coated urea (PCU/SCU)
NPK fertilizer coating to improve storage and handling
Organic fertilizer coating for odor control and slow-release
Export-grade fertilizer production requiring value-added treatments
Anti-caking systems for bulk blending (BB) fertilizer plants
We help fertilizer manufacturers upgrade their production lines with efficient, automated granule coating systems. Whether you need to coat urea, NPK, or organic fertilizer, our team will deliver a customized solution tailored to your capacity and formula.
