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.

A hammer mill contains a drum in which many little hammers are attached to the inside. As the material goes through the mill, the hammers collide with the material. The force of this collision breaks the material down until it reaches the desired size and passes through a screen. A roller mill uses a more controlled mechanism.
