As the rotation speed of the high-speed vibrating ball mill was not adjustable, the factory default setting of 1200 r/min was used. It is generally believed that the ball mill has good grinding efficiency when the interstitial filling fraction of the material is 0.6-1.2 [49, 50]. The parameter setting of the ball mill is shown in Table 1.

Different types of grinding mills
Autogenous grinding mill: in this grinding mill, rotating drums throws in large balls of matter in a rapid motion. This causes the ball to break and make smaller particles. SAG mill: SAG is the short form of semi autogenous grinding. The difference between autogenous and SAG mills is, it uses balls to grind like ball grinding mill.

Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation. The main factor contributing is the shear force applied by the balls. Using only shear force, one can produce large graphene flakes.
