FIELD: chemistry.
SUBSTANCE: method includes a stage of separation of a granulated charge into fine, trade and coarse fractions with milling the coarse fraction and return of fine fraction, milled coarse fraction and a part of the trade fraction into the process as a recycle, in which the part of the trade fraction, being returned into the recycle is separated into two flows, one of which is subjected to milling, with the said flow being taken off in the quantity, necessary for obtaining a charge with a specified equivalent particle diameter.
EFFECT: method makes it possible to stabilise the process of granulation on the whole and obtain a stable final product without changing technological parameters of production.
