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.

Abstract. In hammer mills, the grinding process consists of hitting the material by hammers, articulated on a rotor. It is important, however, that the percussions applied to the hammer are not transmitted to the articulation. The position of the hammer articulation should be determined so that the percussion given by the collision with the ...
