Chemical Pure Ammonium Nitrate vs Porous Prills Ammonium Nitrate

1.Chemical Pure Ammonium Nitrate

Chemical Pure Ammonium Nitrate(CPAN) is produced by melt prilling to form dense solid particles. It cannot absorb diesel oil. If used for ANFO, diesel will separate and flow out.

Typical usage: Chemical Pure Ammonium Nitrate is dissolved by heating, mixed with sodium nitrate and water to prepare water‑phase solution for emulsion explosives.

2.Porous Prills Ammonium Nitrate

For manufacturing process, molten ammonium nitrate mixed with foaming agent. Micro‑pores are formed inside particles during prilling.

Micro‑pores can retain diesel oil firmly to make low‑cost ANFO(Ammonium Nitrate Fuel Oil) for large‑scale open‑pit blasting. Porous Prills Ammonium Nitrate (PPAN) can also be dissolved for emulsion explosives, but it is seldom adopted for this purpose for higher cost.

3.Advantages of two kinds of Ammonium Nitrate

For Chemical Pure Ammonium Nitrate, it has low cost, and its high particle density, low caking tendency. What's more, it has excellent solubility in hot water and wide‑ranging usability for chemical processing. Moreover, it is famous for its good compatibility with sodium nitrate.

For Porous Prills Ammonium Nitrate, it has high oil‑absorption performance and simple on‑site mixing for ANFO. Besides, it has good detonation performance after mixing with fuel oil, and it is also dissolvable for emulsion explosives.
