Morphology
The meaning 'a wheel used to drive machinery in a mill' is directly derivable from combining 'mill' (a facility for processing materials) and 'wheel' (a rotating object); a B1 learner who knows both words will readily interpret it as the wheel belonging to or used by a mill. This noun–noun compositional pattern is common and cross-linguistically transparent, so no idiomatic knowledge is required.
Etymology
The noun mill wheel comes from the simple image of a large wheel beside a river that flowing water pushes to turn the mill's machines. So mill wheel means the big water wheel that 'powers' the mill.
