Chemical synthesis of single‐layer graphene by using ball
Ball-milling is the most common process for graphene synthesis. In several studies, the mill was run in different features [, , ]. Edge-carboxylate graphite (ECG) was produced by ball milling and analysed by using a finite-element method. The ball-mill machine runs 48 times at 500 rpm, each time with 50 min of ball-milling and 10 min of rest.

Ball Mill: Operating principles, components, Uses
The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
