The mineral agitation barrel is driven by the electric motor to rotate the impeller, and the upper and lower circulation stirring is carried out in the tank body, so that the medicine and the slurry are well mixed uniformly, and the necessary reaction equipment for increasing the reaction time of the medicine is enhanced. It is mainly used for better beneficiation operation before flotation. The mixing barrel of Bailing Mine has compact structure and good sealing performance, and a gray ash plate is arranged at the feeding port to prevent the water mist from collapsing. Stir well, the mixing blade is fan-shaped, and the contact area with the medium is large when stirring. The nozzles are arranged in multiple rows, and the water volume is uniform and adjustable. Advanced performance, stable quality of finished products, uniform mixing and rapid discharge.
