Ammonium Nitrate Plants for sale

The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid. Ammonia is used in its anhydrous form gas and the nitric acid is concentrated. This reaction is violent owing to its high exothermic nature. After the solution is formed, typically at about 83% concentration, the excess water is evaporated to an ammonium nitrate (AN) content of 95% to 99.9% concentration (AN melt), depending on grade. The AN melt is then made into "prills" or small beads in a spray tower, or into granules by spraying and tumbling in a rotating drum. The prills or granules may be further dried, cooled, and then coated to prevent caking. These prills or granules are the typical AN products in commerce.
