High-Nitrogen Compound Fertilizer Production Process: Key Steps to Overcoming Granulation Challenges
Among the NPK compound fertilizer family, high-nitrogen formulations (such as 30-10-10 and 25-5-10) are favored by farmers of field crops such as corn and rice due to their rapid action and significant yield increases. However, the special characteristics of high-nitrogen raw materials—urea's strong hygroscopicity and the easy volatility of ammonium salts—pose serious challenges to production: granulation easily leads to clumping, significant nitrogen loss occurs during drying, and clumping frequently occurs during finished product storage. This article will analyze the core processing steps of high-nitrogen compound fertilizers to help companies overcome technical bottlenecks.
