A method for charging blast furnace raw material into a blast furnace, includes, when charging blast furnace raw material including coke and ore material such as sintered ore, pellet, or lump ore into the blast furnace using a rotating chute: mixing the ore material with the coke to produce mixed material; and charging the mixed material into the blast furnace to form a mixed layer in a predetermined region in the blast furnace, in which the mixed material is discharged into the blast furnace at a discharge rate of 1.5 t/s or more to thereby improve homogeneity of the mixed layer.
