accomplished during grinding in ball-and-tube mills or roller mills. While thermal energy for drying can be supplied by exhaust gases from separate, direct-fired coal, oil, or gas burners, the most efficient and widely used source of heat for drying is the hot exit gases from the pyroprocessing system.

Mashing - Whisky

In roller mills, the grain is pressed between stacked pairs of rollers, where the strong pressure causes it to fragment. The smooth rollers can rotate at different speeds to increase the thrust force. The slow speeds do not heat the grain and there is no associated loss of moisture. Roller mills are used as standard for malted barley. Well ...

Feed Mill Machinery Glossary | FeedMachinery

For improved size reduction one of the rolls rotates faster. This results in a differential in speed between the roll pair. Typical differentials range from 1.2:1 to 2.0:1 (fast to slow). Typical roll speeds would be 1,300 feet per minute (~ 395 m/min) for a 9-inch (~23 cm) roll to 3,140 feet per minute (~957 m/min) for a 12-inch (~30.5 cm) roll.
