Ammonumn Nitrate Porous Prill (ANPP) is a critical raw material used in the manufacture of explosives – the most common of which is Ammonium Nitrate Fuel Oil (ANFO). With quality porous prills, sufficient oil is easily and evenly absorbed into the prill micropores to result in a clean explosive with maximum energy release. We use world-class advanced prilling technology to ensure a consistent quality of hard and highly sensitive prills suitable for all blasting applications. Description ANPP is essentially ammonium nitrate (NH4NO3 ) in the form of coarse, porous, hardened spherical particles obtained by spraying the melted product. The material is treated with an anti-caking agent. Use ANPP is used in the manufacture of blasting explosives. Benefits • Cost-effective • Consistent prill quality • Convenient – mixed at the borehole • Easily primed • Safe and reliable
