Zusammenfassung:	A process for the production of explosives grade ammonium nitrate prill (EGAN) comprises the steps of (A). producing seed ammonium nitrate prill as substantially monosized prills; and then (B). fattening using melt/solution of ammonium or mixed nitrates, with drying and thermal treatments, the seed prill in an inclined rotating jacketed pan granulator or a cascade of such pans to produce a final fattened EGAN prill product preferably having at most about 4 mm diameter.
