This kind of agitator is an axial-flow agitator, which can produce large axial circulation and fully react between materials by strong axial convection. This agitator is a series of products formed by our company and scientific research institute with reference to the mixing technology of Laining company in the United States. The agitator blade has equal pitch curved surface, good discharge performance and low shear force. Under the same effect, the power is saved by 30%. It is especially suitable for solid-liquid suspension operation. According to the different suspension requirements of process conditions, the installation angle of the blade can be adjusted. It is widely used in the mixing, heat transfer, dissolution and reaction of low, medium and high viscosity.
