Grinding mills are classified by the media used for grinding. The more common types of mills are: Ball mills - These mills use forged steel balls up to 5 inches (127 mm) in diameter to crush and grind the material. Mill length is two or more times its diameter. Rod mills - Steel rods up to 4.5 inches (114 mm) in diameter
