The design adopts low-speed, large impeller scheme, and is equipped with a baffle and a baffle structure design, so that the slurry flow forms a “W” flow direction, thereby achieving low energy consumption, low wear, and effectively extending the overall life of the equipment. High stirring intensity, no sinking, high slurry levitation, guide cone at the bottom of the tank to eliminate the “dead angle” of mixing, avoiding particle deposition, can be used for ore density ≥3.0t/m3, pulp concentration 30~50% The high-concentration slurry is stirred; the material (pulp) enters the cone cylinder from the upper side of the tank body and is initially mixed with the agent added from the top of the tank, and then enters the center of the tank body, and the material (pulp) is discharged from the upper overflow port after being stirred and mixed. Prevent the material from being "short-circuited" while allowing the agent to function adequately on the surface of the material.
