Zusammenfassung:	FIELD: inorganic compounds technology. SUBSTANCE: process comprises mixing powdered aluminum fluoride with liquid component (water or supersaturated aluminum fluoride solution), granulation of resulting mixture, and heat treatment of granules at elevated temperature. Mixing of components is first effected on blade-turbine granulator at rotor rotation speed 500 to 1500 min-1 until moisture of mixture 18-25% is attained, after which mixture is once more granulated on the same granulator to achieve desired granulation composition of product. EFFECT: increased strength of granules and reduced power consumption. 3 cl, 4 ex
