What is a Hammer Mill? - wiseGEEK

A hammer mill is a machine used to shred or crush materials into smaller pieces. The basic design of machines of this type involve a rotating shaft to which free-swinging hammers are attached. This assembly is enclosed by a drum which holds the material to be pulverized.
