Ball mill drums offer an efficient and inexpensive way to grind materials down to a more usable size, often as fine as 25-75 microns. Both continuous and batch style ball mills use centrifugal force, gravity and hard media to break up industrial materials into fine pieces or powder. Ball milling systems grind dry material and wet slurry alike.

The kwhr/ton requirement in pulverization which has no correction for differences in fineness produced, ranged from 23.3 to 29.3 for the ball mill and from 23.0 to 38.0 kwhr/ton for the hammermill. Pulverization of the lignite from the Indianhead mine in the hammermill is again the exception; this required 46.0 kwhr/ton.
For soft sample materials, other mill types, for example rotor mills, are better suited. ... Planetary ball mills are used for pulverizing solid sample materials by impact and friction. The extremely high centrifugal forces result in very high pulverization energy and therefore short grinding times. Planetary ball mills are available with one ...

mill is the limiting factor for long-term, permanent installations, as it is a high-wear, high maintenance machine. A ball mill is a logical and more permanent upgrade that can be installed later, to replace the hammer mill. With a ball mill, the turn-key ore processor is suited to run for 10,000s of tons with only routine maintenance.
