METHOD OF FABRICATING GRANULATED PHOSPHORUS FERTILIZERS Russian patent published in 1999 - IPC

Abstract RU 2130914 C1

FIELD: inorganic fertilizers. SUBSTANCE: phosphate pulp is cooled to 20-100 C to form 1 to 100% of crystal hydrates in presence of binding additives, after which pulp is granulated to residual free moisture 0.01 to 2%. EFFECT: simplified process due to eliminated drying in furnace gas and improved environmental condition. 7 ex
