More Information
Summary:production of granulated potassium chloride. SUBSTANCE: method includes dedusting potassium chloride in fluidized bed, wetting and drying granules of product followed by conditioning the product with organic agents and cooling; wetting and drying are performed simultaneously in fluidized bed making use of potassium chloride suspension in saturated solution at L: S= 0.7-2.5; drying is performed at temperature above 100 C; in case product contains chlorides of alkaline-earth metals, conditioning is additionally performed with the aid of mineral agents bonding ions of metal forming nonhygroscopic products. EFFECT: improved physico-chemical properties of product. 3 cl, 1 tbl, 3 ex
