Hammer mills work on the principle that most materials will crush, shatter or pulverize upon impact. The Process: • Material is fed into the mill's chamber through the feed chute, typically by gravity. • The material is struck by ganged hammers (generally rectangular pieces of hardened steel) which are attached to
