Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a production method whereby a granular fertilizer composition having high particle hardness can be obtained, in which generation of dust is little in a production process because loss in particle size regulation is little during particle size regulation, and occurrence of solidification is also little because degradation of the granular fertilizer composition is little during custody of a fertilizer.SOLUTION: In a production method of a granular fertilizer composition for performing particle size regulation and classification, after obtaining a granulated material by granulating the fertilizer composition, after granulating the fertilizer composition, a particle hardness of the granulated material is raised to 3 kgf or more, and then particle size regulation is performed.SELECTED DRAWING: None
