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.
