The calculations indicate that in order to obtain overload with smaller mills at a constant circulating load, the L/D ratios would have to increase progressively from the initial /1 value for a n diameter mill, to a /1 L/D value for a throughput reduction to 10 percent of the original value. This high an L/D ratio is without precedent.

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].

These are: Comminution (crushing and grinding). Beneficiation (separation and concentration). Smelting and refining. Ball mills are employed in the comminution stage as grinding machines ( size reduction ). The purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock.
