A particulate mixer is provided to widen a range of the mixing current by forming the three-dimensional chaotic mixing current of particulates by breaking down the particulates at an inclined part by gravity by forming forehead cone-shaped inclined surfaces at both ends of a drum and difference of circumferential velocity of paddles generated by difference between the radial lengths of the inner and outer paddles. A particulate mixer is composed of: a body unit having a cylindrical drum and a particulate mixing chamber; a rotary shaft(5) horizontally disposed in the particulate mixing chamber and rotatably supported to the body unit; and paddles(8a-8d) comprising paddle arms(6a-6d) protruded in a radial direction of the rotary shaft and stirring blades(7a-7d) installed at the paddle arm. Plural paddles are installed in an axial direction of the rotary shaft. The drum has a center part(20) and side parts(21) connected to the center part. A radius of the lower side of the side part is reduced from the inside of the axial direction toward the outside. The length of the radial direction of the paddle corresponding to the center part is longer than the length of the radial direction of the paddle corresponding to the side part.
