    摘要： Provided is a method for producing a mixture, comprising a mixing step for mixing a slurry prepared by dispersing a filler containing carbon black and a rubber liquid prepared by dispersing or the like a rubber component. In the above producing method, the carbon black contained in the slurry has a surface average acidic functional group amount (μeq/m2) of 0.40 or more and less than 3.00; a pH of the slurry is 8 or more; the sum total of the solid matter concentrations of the slurry and the rubber liquid is 20% by mass or less; a mixing equipment used has one or more rotors disposed rotatably in a rotation axis direction and one or more stators disposed unrotatably in the rotation axis direction; the rotors and the stators have plural projections which are arranged circularly with the rotation axis set as the center; rings are formed concentrically by the projections in a single stage or a multistage; and the slurry and the rubber liquid are allowed to pass through a space between the rotors and the stators while the rotors rotate, whereby the mixing is carried out to produce the mixture.
