Ammonification Granultion Reaction of sulfuric acid and ammonia Complete Fertilizer
■ Technical description
◎ Compound fertilizer raw materials and liquid ammonia from ammonia station, sulfuric acid sent by sulfuric acid pump, part of the washing liquid, mixed reaction in the pelletizing area of the pelletizing machine, sulfuric acid and ammonia reaction heat to generate high temperature and low humidity ammonium sulfate slurry, through its own atomizing steam, promote the granulation of granulating materials, and improve the physical properties of pelletizing materials. At the same time, part of liquid ammonia further reacts with ammonium phosphate in the granulation bed to participate in granulation. The granulation temperature is 60~75℃, and the water content of the material after granulation is about 2.5%. The inlet temperature of the dryer is 80~165℃ (according to the needs of the formula, flexible control) the granulation tail gas is washed by the uri system, and the washing liquid can participate in the granulation cycle according to the amount of the formula.
