A hammer mill is a mill whose purpose is to shred or crush aggregate material into smaller pieces by the repeated blows of small hammers. These machines have numerous industrial applications, including: Ethanol plants (grains) A farm machine, which mills grain into coarse flour to be fed to livestock. Fluff pulp defiberizing.

The working principle of the hammer mill is simple to understand. The principle is illustrated in Fig. 1 (a). It only requires choosing an appropriate motor, crushing hammers/knives and material to be crushed. It operates on the principle of impact between rapidly moving hammers mounted on the rotor and the stationary powder bed.
