A] Hammer Mill Working Principle and Main Components. The process of size reduction (for feed material) is carried out by rectangular pieces of hardened steel that rotate inside the chamber at a high speed, striking the material to be milled with a powerful force. These radially swinging hammers (from the turning central shaft) help crush/grind ...

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.
