Investigation of particles with high crack density
Product particle size distribution (PSD) from the tests performed using the cone crusher and three pressure settings of the HPGR. As discussed in introduction, in the HPGR the particles are broken by compression in a packed particle bed; this compression is achieved by applying high pressure, which was allowed to reach 120 bars in this study ...
