METHOD FOR PRODUCTION OF NITROGEN-PHOSPHOROUS FERTILIZER HAVING DELAYED ACTION Russian patent published in 1997 - IPC

Abstract RU 2096395 C1

FIELD: production of granulated ammophos, nitroammophos and diammophos. SUBSTANCE: mixing and granulation of pulp of nitrogen-phosphorous fertilizer is carried out at 70-100 C in the presence of zeolite of 0.3-3.0 mm fraction, mass ratio of zeolite and pulp is 1:0.2-4.7. Then granules are dried at 105-145 C. Zeolite is heated to 100-250 C before it is added into pulp of fertilizer, the process takes place within 20-40 min. EFFECT: prolonged action. 2 cl, 3 tbl
