Size reduction by crushing has a size limitation for the final products. If further reduction is required, below 5- 20mm, grinding processes should be used. Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are:

Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times ( thousands of kw compared to tens in crushing). Because as far as we go to finer size we need more force and collosions for further size reduction.

Regardless of the grinding wheel, though, all grinding processes use abrasive particles to "grind" away material from a workpiece's surface. When a workpiece is exposed to a grinding wheel, some of its material will rub off. With that said, grinding is often used to both remove material from workpieces as well as polish workpieces.
