Flotation size mixing stirring barrel capable of improving size mixing effect

The utility model relates to the technical field of mineral flotation, in particular to a flotation size mixing stirring barrel capable of improving the size mixing effect. Comprising a stirring barrel body, a stirring device and a spiral wire ball arranged on the inner bottom face of the stirring barrel, the stirring end of the stirring device extends into the stirring barrel along the axis of the stirring barrel, the spiral wire ball is a sphere-like spring formed by a metal wire in a spiral extending mode in the single direction, and the sphere-like spring takes the single direction as the central axis. One end, passing through the central axis, of the spiral wire ball is detachably connected with the inner bottom surface of the stirring barrel; and a stop lever is also arranged in the stirring barrel in the direction parallel to the axis of the stirring barrel. The stirring barrel is simple in structure and convenient to use, the turbulence intensity of the bottom of the stirring barrel is enhanced throug
