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 ...Web
