in engineering, fine crushing of a solid material (to particles of less than 5 mm). Pulverization is used extensively for the concentration of mineral products in mining, as well as in metallurgy, the chemical industry, and construction. Pulverization has been known since ancient times. The stone mortar and pestle were known earlier than 8000 B.C.
