Ball Milling - an overview ScienceDirect Topics
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].

Investigation of mechanical activation effect on high-volume
The hybrid grinding method integrated with roller press and ball mill was determined to be the best mechanical activation method for high-volume natural pozzolanic cements. This hybrid application has shown that the grinding process with small grinding ratio and step-by-step completion is more energy-saving and short grinding duration than that with
