How Does a Hammer Mill Work?
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 thatHammer mills are a very common comminution equipment found all across process industries Hammer mills are part of the impact mill family, which means that the milling effect is obtained thanks to the speed at which particles are impacted, here, by one or several rotors 2 Hammer mill working principleHammer mills : Overview Buying guide
