It is widely used in civil engineering. Traditional mixing devices mostly use a mixing rod to stir the concrete in a flow manner, and drive the overall mixing through local activities. However, for concrete, due to its colloidal properties, it has a high viscosity and low fluidity. It is difficult for traditional mixing rods to drive the overall flow mixing. In addition, the inner wall of the mixing device is prone to adhesion and solidification problems, and the concrete will also be stratified, affecting the discharge rate and quality.
