Identification of the grinding mechanisms and their

2009-10-1  The objective of the work was to determine the grinding mechanisms in a stirred ball mill by using population balances. The main grinding mechanisms are cleavage and some fracture for coarse particles ( 15 μ m ) , cleavage and abrasion for intermediate particles ( 0.8 μ m ) and cleavage for fine particles (relative size smaller than 0.15 μ m ).

Effect of ball-milling and graphene contents on the ...

2017-1-15  With increasing the ball-milling time, the dispersion of GNSs in the copper matrix becomes better. However, more defects or disorder structures appear in GNSs. The reason may be that the accumulated energy during ball-milling is larger than the chemical energy of C C bond. In order to achieve a uniform dispersion of GNSs in the copper matrix and relatively complete graphene
