Mill power for conical (Hardinge) type ball mills

It has been found that a change in density of 2.6 to 2.9 (an increase of density of 11.5%) gives a 1.5% increase in mill power for these conical mills, for Pb = 7.75. Inserting p51 = 2.6, Pb = 7.75 and solving for fc gives 0.445, and using the estimate for c, f ~ 1.0. Thus it appears that the powder in the mill is circulating in about the same ...

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].
