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
Uniform pastille size and shape
Improves bulk handling, reduces dust during transport, and ensures consistent dissolution rates.
Low dust and fines
The drop-forming and rapid solidification produce nearly dust-free pastilles, enhancing safety in AN storage and blending.
Thermal management
Independent cooling zones allow precise temperature control to avoid phase transition issues, even at high throughputs.
Corrosion-resistant design
All AN-contact components use stainless steel or engineered polymers, extending service life in aggressive nitrate environments.
Low energy consumption
Direct belt cooling is more efficient than air-cooling systems, and no downstream crushing or screening is required.
Easy cleaning and maintenance
Modular belt sections, accessible spray nozzles, and quick-release scrapers reduce downtime and simplify sanitation.

Frequently Asked Questions
Q: How does the ammonium nitrate steel belt pelletizer operate?
It operates by feeding molten ammonium nitrate onto a continuously moving stainless steel belt via a distributor. The melt is deposited in controlled droplets, which rapidly solidify into uniform pellets in a cooling zone before discharge.
Q: What challenges of granulating ammonium nitrate does this system resolve?
It resolves issues associated with the material's hygroscopic nature, tendency to absorb moisture, thermal sensitivity, and narrow solidification range, thereby preventing deformation, agglomeration, and dust formation.
Q: What production capacities can this equipment handle?
The system is 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.
Q: Why is this pelletizer considered highly corrosion-resistant?
All components that come into direct contact with the aggressive ammonium nitrate environment are constructed from stainless steel or high-grade engineered polymers.
Q: How does the steel belt pelletizer achieve low energy consumption?
Direct belt cooling is highly thermal-efficient compared to air-cooling systems. Additionally, the process yields ready-to-use pastilles directly, removing the need for downstream crushing or screening.
Q: Is the system easy to clean and maintain?
Yes, the design features modular belt sections, accessible water spray nozzles, and quick-release scrapers to minimize maintenance downtime and simplify sanitation.
