How Does a Hammer Mill Work?
2020-11-11 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 a . shaft. that ...
