2020-11-11  before it can exit the mill. 2. Rotor Speed. The faster the rotor speed, the more severe and greater the number of times the hammers will impact the material, producing a finer finished particle size. Conversely, a slower rotor speed equates to fewer hammer impacts, and a coarser end product with fewer fines generated. 3. Hammer size and number.

Size reduction is also used to modify the physical characteristics of ingredients resulting in improved mixing, pelleting, and, in some instances, handling or transport. 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
