carried out by size reduction performed by crushers and grinding mills. The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments

Handbook of Machining with Grinding Wheels

Grinding, once considered primarily a finishing operation involving low rates of removal, has evolved as a major competi-tor to cutting, as the term "abrasive machining" suggests. This is what Milton Shaw, the man who is considered the great pioneer and father of American grinding, said about 10 years ago. Shaw led the development of grinding in the United States over the last 50 years. We
