Design of hammer mills for optimum performance
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 ...

Overall, hammer 2 produced the best improve-ments in grinder capacity, with an average improvement of 200%. Although the hammer 1 design did not per-form as well as the baseline hammer for switchgrass, it is likely that the moisture content caused the decrease in performance rather than the hammer type.
