A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Dry milling (Fig. 7.1) involves grinding the incoming grain, then processing it through a series of steps to liquefy the flour and generate fermentable sugars.Amylases are added at two points in the process—the initial slurry step, and the liquefaction step, which follows a jet cooking operation that uses high-temperature steam to swell the starch.

To do otherwise—that is, to run both wet and dry—might result in shocking a hot tool with coolant, potentially accelerating tool failure. If for some reason a part does calls for dry machining in one region of the part followed by wet machining in another, the shop is careful to insert a delay into the process to let the tool cool down gradually before coolant is applied.

The kinetics of dry grinding of several cement clinkers and two coals were investigated in a laboratory tumbling ball mill. The kinetic process is first-order at first, but the rates of breakage decrease as fines accumulate in the bed. It was demonstrated that the slowing of the breakage rates applies to all sizes in the mill, indicating that

Attrition mills effectively mill metals in inert atmospheres, such as in solid-state 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
