Stirring impeller

Stirring impeller is also called impeller mixer and stirring blade. There are many types of mixing impellers. In general, mixer impellers fall into two categories: for low-viscosity liquids and for high-viscosity liquids.
Paddle type, curved blade type turbine, hinge type turbine, disc type turbine, push type, Bruma gold, tooth plate are suitable for stirring low viscosity liquids. In turbulent flow conditions, the ratio d/D of the impeller diameter d to the groove inner diameter D is usually about 0.3 to 0.6.
