Is that your entire geometry? If so, you do not need MRF's

If the tank is cylindrical and shares the same axis as the rotor, why not just have a SRF with counter rotating walls? There is no need for MRFs in this case.

please help me

Thank you so much

I think that I cant use SRf because:
"Many problems involve multiple moving parts or contain stationary surfaces which are not surfaces of revolution (and therefore cannot be used with the Single Reference Frame modeling approach)"

I used mrf and results were satisfactory(by another geometry for impeller).
please help me about meshing this geometry

Looking at your geometry, every other surface except the mixer is a surface of revolution. Read Fluent User Guide 9.2.2.1.1, it is exactly the same as your case.

Your case is much simpler than this one. So you can easily mesh it with full Hexa

Do you have complete geometry of your model? did you make it any CAD software or ANSYS? Can you share it?

Two blades are still remaining. Other two are blocked with o-grid.
