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].

In this case the grinding circuit comprises an open circuit rod mill followed by a closedcircuit ball mill. The ball mill is most often closed over a classifier like a hydro cyclone (Fig. ) or DSM style screen with a fine cut of mm. The course material is returned to the ball mill feed and the fine screen underflow reports to the ...

Attrition mills effectively mill metals in inert atmospheres, such as in solidstate or mechanical alloying processes, but are not cost effective. Product output is relatively low with attrition mills, compared to large tumbler and vibratory ball mills. Consequently, tumbler ball mills usually are used for production runs of over 135 to 180 kg ...
