Working of Hammer Mill. Feed is introduced from the top of the mill. As the feed enters the grinding zone, it is size reduced by the swing hammers by beating. From here, the particles are further size reduced by the action of stationary anvil and by the rubbing action of hammer mill. The powder is screened and then discharged through the outlet.
