Embodiment 1
[0033] Embodiment 1 Adopt the first technical scheme (spray granulation method) process flow of the present invention such as image 3 : the temperature is 140 ℃, concentration is the ammonium nitrate concentrated solution of 96.0wt% through the nozzle spray granulation that is positioned at the top of the prilling tower, obtains the spherical granular or ellipsoidal ammonium nitrate that contains about 3.0wt% moisture at the bottom of the tower; Then in This ammonium nitrate particle surface evenly sprays 0.05wt% commercially available cationic surfactant stearylamine acetate and 0.2 wt% water-repellent liquid paraffin; The temperature inside the machine is controlled at about 140°C, and the pressure is lower than -0.08Mpa; the material stays in the machine for about 5-8 minutes, and it is the product of the present invention after being discharged.
[0034] The measured average bulk density of microporous ammonium nitrate is 0.73g / cm 2 , the average oil absorption rate is 1...
Embodiment 2
[0035]Embodiment 2 The first technical solution of the present invention is adopted: the ammonium nitrate concentrated solution with a temperature of 165° C. and a concentration of 99.0 wt% is sprayed and granulated through a spray nozzle located at the top of the prilling tower, and about 0.5 wt% of water is obtained at the bottom of the tower. Spherical or ellipsoidal ammonium nitrate; then evenly spray 0.1wt% commercially available cationic surfactant dodecyltrimethylamine on the surface of this ammonium nitrate particle; then put this ammonium nitrate into drum granulation In the machine, the temperature inside the machine is controlled at about 100°C, and the pressure is lower than -0.07Mpa; the material stays in the machine for about 8-10 minutes, and it is the product of the present invention after being discharged.
[0036] The measured average bulk density of microporous ammonium nitrate is 0.71g / cm 2 , The average oil absorption rate is 20.5%; the critical diameter o...
Embodiment 3
[0037] Embodiment 3 The first technical solution of the present invention is adopted: the ammonium nitrate concentrated solution with a temperature of 155°C and a concentration of 97.5wt% is sprayed and granulated through a nozzle located at the top of the prilling tower, and at the bottom of the tower, about 2.0wt% moisture is obtained. Spherical or ellipsoidal ammonium nitrate; then evenly spray 0.1wt% commercially available dodecyltrimethylammonium chloride and 0.1wt% nonionic surfactant acrylate on the surface of this ammonium nitrate particle; The ammonium nitrate is put into the rotary drum granulator, the temperature inside the machine is controlled at about 125°C, and the pressure is lower than -0.08Mpa; the material stays in the machine for about 10-12 minutes, and the product of the present invention is obtained after being discharged.
[0038] The measured average bulk density of microporous ammonium nitrate is 0.71g / cm 2 , The average oil absorption rate is 21.1%;...
