Dual-Source Granulation: The Synergistic Secret of Organic-Inorganic Compound Fertilizers
The challenge in granulating organic-inorganic compound fertilizers lies in the physical incompatibility between the high moisture content (40%-60%) of organic matter and the low moisture content (3%-5%) of inorganic salts. Through a synergistic granulation technology involving stepwise premixing, steam conditioning, and extrusion molding, the pelleting rate can be increased from 55% in a single process to 88%, while simultaneously achieving a slow-release structure where organic matter encapsulates the inorganic core.
