11/1/  · Ball milling method (High energy ball milling method) for the preparation of Nanomaterials, Nano Science and Nano Technology.

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 the system for discharging the output product.

High-energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls. High-energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that cannot be made by conventional powder metallurgy methods.

In comparison with conventional ball mills, Attritors use fewer resources, including: Time, Energy, Media; Plant Space ; In addition, Attritors offer the advantage of being able to take samples at any time and making formulation adjustments during high energy ball milling. Alternatively, ball mills are closed systems and do not offer these

Milling was then performed in 80% ethanol for 30–120 minutes using a high-energy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intra-fibre swelling.
