Why and how to choose solvent in ball milling?

The planetary ball mill can be used for dry grinding and wet grinding. The effect of wet grinding is better than dry grinding, It is believed to be more efficient to get smaller particles as the liquid helps to lower the surface energy of particles. Any solvent which do not react with your material and jars (and balls) can be used. People ofen ...

Ball Milling

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. 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].
