High energy ball milling process for nanomaterial

Besides materials synthesis, high-energy ball milling is a way of modifying the conditions in which chemical reactions usually take place either by changing the reactivity of as-milled solids (mechanical activation — increasing reaction rates, lowering reaction temperature of the ground powders)—or by inducing chemical reactions during milling (mechanochemistry)

The high-energy ball mill processing can be divided in three main groups according to the mechanisms involved and/or the purpose envisaged: Mechanophysical conditioning, Mechanochemical synthesis

Ball Milling - an overview | ScienceDirect Topics

Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force.In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear and
