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.

Hammer mill is one of the machines used in size reduction. Hammer mills reduce particle size by breaking due to the impact of the hammers, shearing by the edge of the hammers and screen, and collision among the product and in between the product and machine. The impact is the primary force to reduce particle size in a hammer mill.
