The blades of the inclined blade disc turbine impeller have a certain angle, providing axial flow and good circulation performance. The shear force is lower than that of a flat-blade disc turbine. The blades of the pitched-blade disc turbine impeller have a larger backward angle, offering good discharge performance and low energy consumption. This impeller is especially suitable for the mixing and dispersion of heterogeneous materials. It is also used in general heat transfer, emulsification, and other operations
