PROCESS OF PRODUCTION OF GRANULATED COMBINED FERTILIZER Russian patent published in 1995 - IPC

Abstract SU 1824754 A1

FIELD: agriculture. SUBSTANCE: evaporated pulp of nitrate-phosphate solution is sprayed into drum granulator-dryer into curtain of particles of combined fertilizer formed with external and internal recycle, granulate is dried and dispersed with extraction of product fraction and fine fraction returned into curtain as external recycle. Amounts of fine fraction returned into curtain as external and internal recycles are controlled. Share of fine fraction returned into curtain is kept within limits 0.8-0.96 of its total amount. 0.04-0.2 of total amount of fin fraction is used for preparation of evaporated pulp. EFFECT: increased operational efficiency of production of granulated combined fertilizer. 2 cl, 1 tbl
