Solid agglomerate method of NPK compound fertilizer production line

Using monomer basic fertilizers such as: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate monoammonium phosphate, diammonium phosphate, heavy calcium, ordinary calcium), potassium chloride (potassium sulfate), etc. as raw materials, they are crushed to After a certain degree of fineness, the material is agglomerated and granulated in the rolling bed of the drum granulator (or disc granulator) through humidification and heating. During the granulation process, it can also be granulated in the drum if conditions permit. The machine adds a small amount of phosphoric acid and ammonia to improve the granulation conditions. The granulated materials are dried, sieved, and cooled to obtain NPK compound fertilizer products. This is also one of the methods widely used in the world. The early United States, India, Japan, Thailand and other Southeast Asian countries used this method for production.
The raw materials of the npk compound fertilizer production line are widely available, the processing process is relatively simple, the investment is small, the production cost is low, the start-up is fast, the production flexibility is large, the product grade adjustment is simple and easy, and the versatility is strong. The reliance on raw materials is not strong. Because it is the secondary processing of basic fertilizers, there is almost no environmental pollution problem. This kind of production technology has become increasingly mature in China.
