I think that I can't use both (symmetry on static domain and rotational periodicity on rotating domain) however static domain is symmetric. And I think that I can't use symmetry for rotating domain. Am I correct?

I'm taking that the red, green and blue arrows are X, Y and Z (as used by DM and Meshing).
The problem with your current geometry is that, because of the rotating domain, the flow isn't symmetric in the XY plane, making your geometry not representative of the flow you're trying to model. But if both outlets have the same operating condition what you can do, however, is use a symmetry for both domains in the XZ plane. The size of your problem should be roughly the same.
