Zusammenfassung:	PROBLEM TO BE SOLVED: To make it possible to regulate the particle size of water-granulated slag obtained by solidifying molten slag by water quenching water so as to allow it to fall within a specification and to simply regulate the particle size of water-granulated slag to a desired particle size. SOLUTION: A method for regulating the particle size of water-granulated slag comprises solidifying molten slag discharged from a melting furnace 2 by water quenching to form water-granulated slag S, conveying the water-granulated slag S to a grinder 4 through a slag conveyor 3, and grinding the water-granulated slag S by means of the grinder 4, wherein the particle size distribution of the water-granulated slag S or the particle size distribution and particle shape of the water-granulated slag are continuously measured, and the operating conditions of the grinder 4 are controlled at optimal ones according to the results of the measurement to regulate the particle size of the water-granulated slag S.
