Ballmilling is the most common process for graphene synthesis. In several studies, the mill was run in different features [,, ]. Edgecarboxylate graphite (ECG) was produced by ball milling and analysed by using a finiteelement method. The ballmill machine runs 48 times at 500 rpm, each time with 50 min of ballmilling and 10 min of rest.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
