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 Impact mills are similar in construction and principal to HSI and VSI crushers. Impact mills are used to pulverize feed material by impact against a surface or a bed of feed material. The feed material may be propelled by gravity or by a rotating impeller or rotor. The impellers or rotors can be vertically or horizontally orientated.

Working of Hammer Mill. The hammer mill works by introducing the material to be ground into the feed hopper. The material is then pulled into the mill by the rotation of the rotor. As the rotor spins, the hammers strike the particles, breaking them down into smaller pieces. The ground material is then discharged through the discharge chute.
