TREATMENT OF AMMONIUM-NITRATE FERTILIZER FOR CAKE PREVENTION

Caking of ammonium nitrate is prevented by coating the finished produc t with inert dust and/or a surfactant and by adding an inorganic salt or nucleating agent (a stabilizer) to the melt prior to prilling. In t he present work, selected locally available anticaking agents are test ed on ammonium nitrate produced in Egyptian fertilizer companies. Anti caking efficiencies are evaluated and compared. Optimum doses for each anticaking agent and anticaking composition are determined by a bench scale experimental technique.
