Two doors (see 4, 9) give access to the construction. Both were
closed and locked so we couldn't enter the workplace.
Fortunately, there was a narrow window opening (9) next to the entrance to the grain mill, and so we could get an idea of its content.
First we have a hurstframe (7, right) with place
for one couple of stones. There is a round dust cover (guardapolvo) topped with a feeding hopper (tolva).
The rest of the feeding system (centrifugal feeder, because the funnel is centered on the stonecase) is absent.
Next to the stones we see a bolting machine (7, left).
I am not sure this is the original configuration. The devices are so close to the walls
and to each other that there doesn't seem to be enough space to work there.
In the background we also see elements that may have belonged to the central eléctrica: possibly a turbine, a dynamo, and a panel with indicators.
