Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
WhatsApp: +86 18037808511High Energy Ball Mill (BM) The objectives of the ball milling process include particle size reduction, mixing or blending, and particle shape changes. The most common mill used for these purposes has been a planetary ball mill; a bowl sits on a grinding platform and rotates in a direction opposite to the direction of the base fixture.
