CONTINUOUS KNEADING DEVICE FOR GRANULAR POWDER AND VISCOUS LIQUID, SYSTEM, AND CONTINUOUS KNEADING METHOD

[Problem] To provide a continuous mixing apparatus, a system, and a continuous mixing method for a powder/granular material and a viscous liquid, capable of effectively mixing a powder/granular material and a viscous liquid even in cases where the particle size of the powder/granular material is small, or in cases where the viscosity of the viscous liquid is high. [Solution] A continuous mixing apparatus for a powder/granular material and a viscous liquid, provided with a mixing cylinder, a shaft member 2 (2A, 2B, 2C, 2D) which is provided on a central axis of the mixing cylinder and which rotates inside the mixing cylinder, and a plurality of mixing paddles 1 (1A, 1B, 1C, 1D) disposed on a surface of the shaft member 2, wherein the mixing cylinder is provided with a powder/granular material feed port on one end portion, a mixed material discharge port on the other end portion, and a viscous liquid injection unit between the powder/granular material feed port and the mixed material discharge port, and wherein the plurality of mixing paddles 1 are disposed on the shaft member 2 so as to form a spiral 101 around the central axis, the plurality of mixing paddles 1 being, in at least a portion between the viscous liquid injection unit and the mixed material discharge port, attached so as to alternately provide first rows 2A, 2C having an attachment angle of 5° to 60°, from the direction of the mixed material discharge port, with respect to the central axis, and second rows 2B, 2D having an attachment angle of -5° to 5° with respect to the central axis.
