Crushing Mineral Processing

In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives: the attainment of a size appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate; or the release of metallic or ore inclusions from an unwanted matrix with a view to maximum separation.

Grinding Machining Process : Complete Notes - mech4study

The selection of the structure of the grinding wheel can be easily understood by the one simple example. The rough grinding on the soft and ductile material done by only open structure because the work piece is soft and ductile therefore the chip flow will be continuous and rough grinding involves more material removal and more space for the chip removal is required.
