METHOD FOR PREPARING AGGLOMERATED POTASSIUM CHLORIDE Russian patent published in 2003 - IPC

FIELD: inorganic chemistry, chemical technology. SUBSTANCE: invention is designated for preparing agglomerated KCl. Method for preparing agglomerated potassium chloride from finely dispersed potassium chloride involves addition reagent promoting to agglomerization to wetted concentrate, mixing charge and its drying in drying apparatus. Potassium chloride forming in processing sylvinite ore is used as a wetted concentrate. Cyclone dust trapped in stage of treatment of foam gases of drying apparatus is added to wetted concentrate. Before drying charge is passed through turbo-bucket mixer-granulator device for charge homogenization by granulation composite, moisture, mechanical activation of potassium chloride particles to obtain granules. The latter is fed to vibroforming device for thickening and rounding granules. Invention allows preparing agglomerated KCl with required properties. EFFECT: improved preparing method. 2 cl, 1 tbl
