Atolia Mine #8

Here is another view of the previously depicted spiral thingamajig. By the way, if you know what this thing is called or what exactly it did, please e-mail me. I suspect something rolled down these spirals in the process of being sorted or separated. This machine is in the same building as a large ball mill (huge rotating cylinder full of steel balls used for crushing rock). I suspect this would have been a very, very noisy place! It was a cool experience photographing its abandoned remains in the complete silence and stillness of the night.
