The magnitude of the difference was slight for Ball Mill-1 (Fig. 11), but it is more obvious for Ball Mill-2 (Fig. 12). Improved fines generation in Survey 2 can be attributed to the increased solid content of the ball milling operations. For both of the ball mills, Survey-2 had higher solid content than Survey-1.

Fig. 2 (c) shows the FTIR spectra of the ball-mill synthesized graphene (SG400), copper oxide incorporated graphene nanocomposites (CuO/SG10, CuO/SG30 and CuO/SG50) and bare copper oxide. A sharp peak around 1570 cm −1 in the FTIR spectra of SG400 and nanocomposites arises due to aromatic C C stretching in graphene [ 54 ].
