Coaxial Dual-Shaft Disperser

The concentric dual-shaft disperser operates by rotating two concentric shafts at different speeds: the inner shaft drives a high-speed dispersion disc to generate shear force, while the outer shaft powers a mixing paddle for blending. It is used for dispersing and mixing high-viscosity materials in industries such as coatings and inks. This design enables simultaneous high-speed dispersion and low-speed stirring, preventing material splashing and bubble formation.
Selection
When selecting a concentric dual-shaft disperser, factors such as material viscosity, processing capacity, and process requirements must be considered. For high-viscosity materials, it is necessary to match the motor power and shaft system strength. The diameter of the dispersion disc should be determined based on the container size, and the speed range should be adjusted to suit different dispersion stages. Additionally, attention should be paid to the corrosion resistance of the materials used, and safety protection features such as overload protection should be verified.
