The fantastic red elevator that is Pool #61, built 1928.
The tallest dock structure is an equipment elevator that connects the many dock levels.
A walk-up service window on the side of an administration building of some sort. I have a feeling the buildings were color coded.
One of my favorite signs, informing workers about to descend into the open-top grain bins about basic procedures. This was in ADM-Annex 1 (connected to the cleaning house via skyway), so it will never be seen again, unless the sign lands luckily when the elevator is demolished.
The bits with handles are the filters with screens of different sizes. Larger grain particles would be stopped at the top for further reduction via the mills, while the powder at the bottom would be run through another bolter–one of the refinement stages in flour production.
