Title says it all; I’m sure a thin layer of cement will be left over after they poor it all, and I would imagine that thin layer would harden and then the next time they use the mixer another thin layer would be leftover and so on and so forth. After a while I would imagine it would accumulate to the point where it renders the mixer unusable.
Why is this not the case?

I met a roided out bodybuilder years ago who delivered us a load of concrete, and he said he climbed into the drums of trucks and would jack hammer them out. Which sounds like the worst job in the world.
