A three bladed axial flow stirrer is a typical axial flow stirrer with high discharge capacity and low shear performance; The use of baffles or deflectors results in stronger axial circulation Because of its strong cycling ability and low power consumption, its advantages can be demonstrated in the application of low viscosity and large capacity homogeneous mixing processes Widely used in processes such as heat transfer, reaction, suspension, and liquid-liquid dissolution in low viscosity liquids When the viscosity of commonly used media is less than 2000mPa. s, the commonly used rotational speed is n=200-900rpm, the DJ/D container diameter is 0.2-0.4, and the solubility is deeper than 7 times that of DJ, a double-layer impeller can be used It can be installed vertically or tilted less than 15 degrees during installation When deviating from the container or installing at an angle, it is equivalent to adding a baffle inside the container.
