Ammonium Nitrate Steel Belt Pelletizer by China Factory – Reliable Suppliers for High-Quality Fertilizer Granulation
Product Video
Long Description
The ammonium nitrate steel belt pelletizer operates by feeding molten ammonium nitrate onto a continuously moving stainless steel belt. Through a specially designed distributor, the melt is evenly dropped onto the belt surface in controlled droplets. As the belt travels through a cooling zone, typically using water spray or air cooling beneath the belt, the droplets solidify into uniform pellets before being discharged at the end of the system.
Ammonium nitrate presents several challenges in the granulation process due to its hygroscopic nature, tendency to absorb moisture, and thermal sensitivity. It also has a relatively narrow solidification range, which requires precise temperature control to avoid deformation, agglomeration, or dust formation. The steel belt pelletizing method effectively addresses these issues by providing rapid, uniform cooling and minimizing particle collision during solidification.
This equipment is designed to handle production capacities from 100 kg/h up to 3000 kg/h, making it suitable for both pilot-scale and industrial-scale operations. The system can be integrated with upstream melting and downstream screening or packaging units to form a complete production line.
Key Advantages
Improves bulk handling, reduces dust during transport, and ensures consistent dissolution rates.
The drop-forming and rapid solidification produce nearly dust-free pastilles, enhancing safety in AN storage and blending.
Independent cooling zones allow precise temperature control to avoid phase transition issues, even at high throughputs.
All AN-contact components use stainless steel or engineered polymers, extending service life in aggressive nitrate environments.
Direct belt cooling is more efficient than air-cooling systems, and no downstream crushing or screening is required.
Modular belt sections, accessible spray nozzles, and quick-release scrapers reduce downtime and simplify sanitation.

Frequently Asked Questions
The system feeds molten ammonium nitrate onto a continuously moving stainless steel belt via a specialized distributor. The melt is dropped in controlled droplets, which solidify into uniform pellets as the belt passes through a cooling zone.
This equipment is highly scalable and designed to handle production capacities ranging from 100 kg/h up to 3000 kg/h, making it suitable for both pilot-scale and large industrial-scale operations.
The steel belt pelletizing method provides rapid, uniform cooling and minimizes particle collision during solidification. This precise temperature control avoids deformation, agglomeration, and dust formation common with thermal-sensitive materials.
All components that come into direct contact with the ammonium nitrate are constructed from high-grade stainless steel or engineered polymers to resist corrosion in aggressive nitrate environments.
No, the direct drop-forming process creates highly uniform pastilles with extremely low dust and fines, eliminating the need for downstream crushing or screening and reducing overall energy consumption.
