Technology of manufacturing expanded ammonium nitrate

In this paper, the ways of manufacturing sensitive ammonium nitrate (AN) are indicated. The mechanism of AN crystals by use of vacuum expand technology, and expanding equipment and the action of expanding agents are emphasis. Improved technical conditions are determined. The method of improving crystallization properties of AN by use of surface active agents is a key of manufacturing excellent expanding AN explosive which is called no-containing TNT or less TNT ammonium nitrate explosive. It may also be the best technical way of manufacturing explosives.
