METHOD OF PRODUCING GRANULAR POTASSIUM CHLORIDE Russian patent published in 2011 - IPC C01D3/22 C01D3/04 B01J2/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry. The method of producing granular potassium chloride involves structural agglomeration of filtered potassium chloride in a turbo blade mixer-granulator, drying and pressing the agglomerated product, grinding the pressed product and sizing the ground product. Structural agglomeration of the potassium chloride is carried out together with fine sizes of the granulation stream obtained after sizing the ground pressed product with the load on the turbo blade mixer-granulator not less than 400 t/m² of its cross section. The agglomeration process is not shorter than 15 seconds.

EFFECT: invention enables to obtain granular potassium chloride with improved rheological properties such as static strength and wearing capacity of granules, not contaminated with structure-forming additives.
