EXPERIMENT AND MODEL-BASED INVESTIGATION OF

2014-12-1  hammer mill and study the breakage and kinematics of the particle motion within the hammer mill. In the simulations, increase in hammer tip speed causes higher frequency of impact of particles per unit time and higher specifi c energy of impact resulting in generation of much fi ner end product. A limit can be conceived during the breakage event.
