Cement Powder

I don't know where to put this but does anybody have any experience with moving cement dust by air thru a hose?

I am looking into building a machine and need to know how much cement dust would move thru a certain diameter hose at 10 psi. Is there a way to figure that out?

Has anybody run a pneumatic semi trailer and hauled the cement powder? Do you know how long it take to unload so much powder?
