Abstract—Waste printed circuit board (PCB) is the most important the slow development minution theory. Fractal
part of Waste electronic and electric equipment (WEEE), and also geometry is a new research method of particle shape in several
one of the most arduous job to deal with because of its decades, which can describe plex structures. Fractal
heterogeneity and plexity. Crushing is the crucial process method provides a novel research method minution
for the technology of recycling waste PCB, for chemical and bio- mechanism of waste PCB.
metallurgy methods, the process of crushing could have enough
chance to make the surface of particles contacting with Fractal theory is a novel way to plex or self-
medicaments, again for physical methods, the process of crushing similarity system morphology of irregular structures in social
could directly cause the efficiency of essive separation, the activities [3]. The research object of fractal theory is a non-
recovery rate and
