Abstract:
1. A method of thermally treating high density ammonium nitrate comprising: loading high density ammonium nitrate into a tank; entering the high density ammonium nitrate into heat treatment equipment, wherein the ammonium nitrate is at room temperature upon entrance; heating the high density ammonium nitrate inside the heat treatment equipment; removing the treated ammonium nitrate from the heat treatment equipment, wherein the exit temperature does not exceed 60° C.; and sieving the treated ammonium nitrate, thereby obtaining thermally treated ammonium nitrate, wherein the high density ammonium nitrate has a bulk density of 0.95-1.00 kilograms per liter (kg/L), a fuel absorption of less than or equal to 4%, and a crushing strength of about 0.2-0.6 kilogram (kg).
