GRANULATED PHOSPHATE-POTASSIUM FERTILIZER PRODUCTION METHOD Russian patent published in 1995 - IPC

Abstract RU 2029756 C1

FIELD: production of fertilizers. SUBSTANCE: method involves pelletizing powder mixture of double or single superphosphate with potassium chloride in the presence of moisture; following drying of granules obtained. Potassium chloride particles have size below 0.2 mm in an amount of 50-95% by weight. Pelletizing of phosphate-potassium fertilizer is conducted at temperature of 20-60 C in pelletizer and with moisture content within the range of 10-19% . EFFECT: increased output and high quality of fertilizer by using potassium chloride particles of above mentioned size to provide homogeneous mixing with powdered superphosphate. 2 cl, 2 tbl
