Can dangerous material be made with a rock tumbler?

rock tumblerMy son is taking chemistry in school and he tells me he’s grinding rocks but I’ve yet to see any rocks. Does this possess a danger?

This should be a harmless activity in that all that is happening is an automatic way to grind down minerals that often result in polished and sometime quite beautiful stones.  Be clear that some tumblers are “on” for weeks in order to polish the stones so electricity costs are a mild consideration.
