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 ...
• Increasing the hammer mill screen size from 1/4-inch to 3/4-inch reduced the grinding energy by more than 3 times. • The particle dimensions changed significantly after grinding in a hammer mill fitted with different screens.
