The paddle type agitator is a kind of agitator with two or three promoting mixing members. The paddle type agitator has a high rotation speed during mixing, which can drive the materials to move along the radial direction, so that the materials can be fully circulated and mixed. The paddle type agitator is good for mixing the materials such as liquid, mixed liquid and emulsion with low mortar consistency.

The propeller type agitator is a widely used axial-flow type high-function agitator, which has a discharge function and low shear stress. Thermal convection circulation occurs at low speed, and seepage occurs at high speed. The large blade inclination angle and blade skewness can make the agitator achieve a high fluidity field during transition flow and even seepage, and the liquid output can be developed by 30% compared with the traditional promoting agitator. It is good for mixing, melting, solid floating, heat conduction, reflecting convection heat transfer, purification and crystal operation of high viscosity.
