Move about in confusion in factory (4)
I believe the answer is:
mill
This clue could be a double definition.
'move about in confusion' is the first definition.
'mill' can be an answer for 'move' (milling is a kind of moving). I'm not sure about the 'about in confusion' bit.
'factory' is the second definition.
(mill is a type of factory)
'in' is the link.
Can you help me to learn more?
(Other definitions for mill that I've seen before include "No fun going through this" , "Flour factory" , "Flour is produced here" , "Grind (grain)" , "Place for grinding flour" .)
