Particle Size Reduction Feed Mill Machinery Glossary

Hammer mills reduce the particle size of materials by impacting a slow moving target, such as a cereal grain, with a rapidly moving hammer. The target has little or no momentum (low kinetic energy), whereas the hammer tip is traveling at a minimum of 4,880 m/min (~16,000 feet per min) and perhaps in excess of 7,015 m/min (~ 23,000 feet per min) (high kinetic energy). The transfer of energy
