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.

The Difference between Crushing and Grinding in mineral processing Both crushing and grinding are size reduction processes. They are known as milling operations Introduction The size reduction operation in the plant takes place as a sequence of crushing and grinding processes. In crushing, particles are reduced in size to such a level that grinding can be conducted, while grinding allows ...

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.
