Ammonium Nitrate Steel Belt Pelletizer - High-Quality Production from China Suppliers and Factory
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
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 solidify into uniform pellets as the belt moves through a cooling zone.
Ammonium nitrate is highly hygroscopic, tends to absorb moisture, is thermally sensitive, and has a narrow solidification range. This requires precise temperature control to avoid deformation, agglomeration, or dust formation during processing.
The equipment 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.
The drop-forming and rapid solidification processes prevent particle collision during cooling, which produces nearly dust-free pastilles and improves overall safety during storage and blending.
All components that come into direct contact with ammonium nitrate are constructed from stainless steel or engineered polymers, ensuring long service life in aggressive nitrate environments.
Yes, direct belt cooling is more efficient than air-cooling systems and eliminates the need for downstream crushing. Additionally, modular belt sections, accessible spray nozzles, and quick-release scrapers simplify cleaning and maintenance.
