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 ...

Hammer mills also generate heat, especially at when run at high speeds, which may be undesirable for certain applications. With regards to particle size, there is great variability when using a hammer mill. This is because particle size is determined only by screen-hole size; meaning that any sized particle under a certain size can pass through.
