English term (edited): "feed bin(s)"

This is the usual translation for feed bins, unless there is some specific term for construction/ civil enginering - I've never heard of feed bins being used to hold stones...

I have googled a bit and found what your text is describing: they are "cold feed bins" and they look like this:

Another document has a drawing which will help you understand how it works (maybe you already know?)

In this drawing they show a silo, so that is not the correct term. Cold feed bins here are open containers like the kind you see on building sites, when there is a lot of rubble to be taken away - a bit like a "skip". Don't know whether there's a specialist term - I would call it a "container" or a "benne" in French...
