Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Crushing & Grinding

As ore is crushed into small pieces in the crushing and grinding mill area, mechanical failures are inevitable for primary, secondary, and tertiary crushers. Our solutions can enable you to maximize availability, extend the lifetime of mechanical equipment, and reduce costs by detecting emerging problems on crushing equipment before they occur.

Aug 01, 2008· This grinding process is very costly and energy consuming; often many times more than the preceding crushing operation. The fact that fine grinding is much more costly and energy consuming than crushing is also reported elsewhere, see for example Eloranta (1997). A finer crushed product will increase output and decrease mill retention time.
