The problem with ball mills is that they can be very heavy and expensive. A small flow-through ball mill like the one above would do nicely in a small hard rock gold mill that processes finely divided gold from a high grade ore. An older, used ball mill, of about 2×4 foot will set you back from $4,000 to $5,000.
