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. that rotates at high speed inside the mill’s . grinding ...

A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the
