METHOD FOR GRANULATION OF MELT OF COMPOSITION BASED ON AQUEOUS NITRATE MINERAL SALT, SYSTEM, AND THEIR USE Russian patent published in 2023 - IPC B01J2/14 C05C1/02 C05C5/04 C05G5/12 

FIELD: chemistry.

SUBSTANCE: present invention relates to a method for control of a temperature in a granulator, in which a melt of a composition based on aqueous nitrate mineral salt is granulated. The method includes stages of granulation of the melt, separation of particles of an insufficient or too large size at an output from the granulator, and recirculation of particles of the insufficient or too large size to the granulator, measurement of a temperature in the granulator, adjustment of a number of particles of the insufficient and too large size, recirculated to the granulator in accordance with the measured temperature in the granulator. The present invention also relates to uncoated granules of a composition based on aqueous nitrate mineral salt with low dust formation.

EFFECT: provision of a method for granulation of a melt of a composition based on aqueous nitrate mineral salt for the production of granules having a round shape and forming the minimum amount of dust.
