autogenous or autogenic mills are socalled due to the selfgrinding of the ore a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. it is similar in operation to a sag mill as described below but does not use steel balls in the mill. also known as rom or "run of mine" grinding.
a typical type of fine grinder is the ball mill. a slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. ball mills normally operate with an approximate ball charge of 30%. ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. the feed is at one end of the cylinder and the discharge is at the other. ball mills are commonly used in the manufacture of portland cementand finer grinding stages of mineral processing. industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 mw motor, drawing approximately 0.0011% of the total worlwikipedia · text under ccbysa licenseglossary of mining terms secdilution (mining) rock that is , by necessity, removed along with the ore in the mining process, subsequently lowering the grade of the ore. semiautogenous grinding (sag) a method of grinding rock into fine powder whereby the grinding media consist of larger chunks of rocks and steel balls.
