Dec 15, 2012#0183;#32;Ball milling of graphite under a hydrogen atmosphere is an effective method of producing nanostructured graphite which is able to store an appreciable amount of hydrogen. Nanostructured graphite has potential for use as a lowcost in energy store, for vehicles and stationary hydrogenenergy applications.
Synthesis of Nanomaterials by High Energy Ball Milling. The impact energy of the milling balls in the normal direction attains a value of up to 40 times higher than that due to gravitational acceleration. Hence, the planetary ball mill can be used for highspeed milling. Schematic view of motion of the ball and powder mixture.

#0183;#32;This process of ball milling is done approximately 100 to 150 hrs to get uniform fine powder. 4. Ball milling is a mechanical process and thus all the structural and chemical changes are produced by mechanical energy. I have seen an interesting image at for ball milling method at wikipedia. You can see the image here. Advantages of ball milling
The balls rotate with high energy inside a drum and then fall on the solid with gravity force and crush the solid into nano crystallites. CONCLUSION The significant advantage of this method is that it can be readily implemented commercially. Ball milling can be used to make carbon nanotubes and boron nitride nanotubes. It is a preferred method

Ball milling is a simple, fast, costeffective green technology with enormous potential. One of the most interesting applications of this technology in the field of cellulose is the preparation and the chemical modification of cellulose nanocrystals and nanofibers. Although a number of studies have been repo Recent Review Articles Nanoscale Advances Most Popular Articles
the milling process takes place during rotation as a result of the transfer of kinetic energy of the moving grinding media into the grinding product. The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and

F. Delogu, G. Mulas, in HighEnergy Ball Milling, 2010. Fundamentals of mechanical alloying processes in ball mills. A ball mill is a relatively simple apparatus in which the motion of the reactor, or of a part of it, induces a series of collisions of balls with each other and with the reactor walls (Suryanarayana, 2001).
