The stirring wing (impeller) is the most important part of the stirring device, classified into axial flow type and radial flow type.
The stirring blade (impeller) is the most important part of the stirring device. The rotational energy generated by the motor is transmitted to the impeller through the shaft and converted into kinetic energy. At this time, pressure shear occurs along with fluid motion, and the characteristics of the blade (impeller) are classified into axial flow type and radial flow type based on the ratio of these factors and the flow pattern created by the discharge flow direction. Impellers are divided into high and medium Reynolds number (Re) regions, and (high), medium, and low Re regions. The high and medium Re regions include classifications such as propellers, high discharge propellers, paddle types, flat paddle types, turbine types (with discs), cone types, and surface aeration types, while the (high), medium, and low Re regions include classifications such as special paddles and ribbon-screw types.
