A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about

Lowcost, highyield production of graphene nanosheets (GNs) is essential for practical applications. We have achieved high yield of edgeselectively carboxylated graphite (ECG) by a simple ball milling of pristine graphite in the presence of dry ice. The resultant ECG is highly dispersable in various solvents to selfexfoliate into single and fewlayer (≤ 5 layers) GNs.
