Daha fazla öğreninGrinding with HPGR led to a broader particle size distribution and a higher fraction of fine particles than BM grinding, while the specific surface area of both samples was almost the same (1810 ± 10 cm 2 /g). Also, the shape of HPGR particles was irregular, angled, and elongated-shaped because of their low sphericity and high aspect ratio.
