China Ammonium Nitrate Steel Belt Pelletizer - High Strength, Uniform Pellets | Suppliers & 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.

Frequently Asked Questions
How does the ammonium nitrate steel belt pelletizer operate?
The pelletizer feeds molten ammonium nitrate onto a continuously moving stainless steel belt. A specially designed distributor drops the melt onto the belt in controlled droplets. As the belt passes through a cooling zone, the droplets solidify into uniform pellets before discharge.
What are the main challenges when granulating ammonium nitrate?
Ammonium nitrate is highly hygroscopic, tends to absorb moisture, and is thermally sensitive. It also has a narrow solidification range, making precise temperature control essential to prevent deformation, agglomeration, or dust formation.
What production capacities can this steel belt pelletizer support?
The equipment is highly versatile and designed to handle production capacities ranging from 100 kg/h up to 3000 kg/h, making it ideal for both pilot-scale testing and large-scale industrial operations.
Why is the steel belt method preferred for thermal management?
It features independent cooling zones that allow precise temperature control. This setup prevents phase transition issues during solidification, even when operating at maximum throughput capacities.
How does the system prevent corrosion from aggressive nitrates?
To ensure a long service life in aggressive nitrate environments, all components that come into direct contact with the ammonium nitrate are constructed from high-grade stainless steel or specialized engineered polymers.
Is downstream crushing or screening required with this system?
No, downstream crushing or screening is not needed. The drop-forming process and rapid belt cooling produce uniform, nearly dust-free pastilles directly, which also helps lower overall energy consumption.
