The town mill(out)

The air inside the mill is thick with a very fine sand. Numerous busy little Hobbits are hard at work, grinding rocks into sand. One particular Hobbit seems to be conducting the chaos with shouts of "Numbskull" and "Meathead". As the plump figures bustle about they create a veritable din from the various tools clanking and hammering about. A large hopper sticks out of the side of a strange looking piece of machinery.
The only obvious exit is out.
