Abstract
A bowl mill has a vertical mechanism to drive a milling bowl and a hot-air supply to an air box positioned below the bowl. An evacuator is positioned in the air box to prevent the box from overflowing when the mill shuts down suddenly. The evacuator has a drive mechanism that is separate from and independent of the mechanism that drives the mill.
