FEECO hammer mills use a central rotating shaft, with several 'hammers' attached to the pivots on the shaft. When the shaft turns, the hammers are swung via rotational energy, which causes them to collide with the material and break it into smaller particles. Hammer mills are relatively flexible units, used in a variety of applications.
