1.4 Spray granulation drying process operating conditions Spray granulation dryer in fertilizer production is widely used. In our country 30,000 tons / year ammonium phosphate universal design that use this equipment. (1) the working condition of the slurry spray gun The pulverization of ammonium phosphate slurry is an important factor affecting the granulation. It affects not only the granulation rate, but also the scarring speed on the inner wall of the dryer. Commonly used air-flow atomizer structure
