Now, A ball mill, rock tumbler, lapidary polisher ect, is a machine which rorates a barrel full of media, like steel or ceramic balls / beads which as the name suggests, tumble over each other. Any meterials caught between the media get grinded, milled and smahed into super fine dust, and if given the time, even go micronic. I used my own mill primarily to make aluminium powder, the most ...
