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
