In a autogenous mill the ore is fed directly into the mill from either the primary crusher or the mine itself. The size of the rock will be between four and eight inches. It will be this type of mill that will use a stock pile instead of a bin as fine ore storage. The feed is large enough that moisture and freezing won't bother it.

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by; a. Residence time of the material in the mill chamber. b. The size, density, and number of the balls. c. The nature of the balls (hardness of the grinding material) d. Feed rate and feed level in the vessel.

Semi-autogenous grinding (SAG) and autogenous grinding mills are used for grinding large chunks of materials into smaller pieces which can be later used for processing. Such mills are used in the primary stage of grinding process where pieces of raw materials need to be grounded for further processing or sorting.

achieve the desired size reduction. Gyratory crushers, jaw crushers, roll crushers, and impact mills are used for primary and secondary crushing. After crushing, the size of the material is further reduced to 50 micrometers ( m) or smaller by grinding, using smooth rolls, media mills, autogenous mills, hammer mills, or jet mills.

Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates.

For fully autogenous grinding the mill drives are usually selected with a rating so that the drive is slightly oversized, to allow for variations in ore specific gravity and charge level. For example, if the ore is quite uniform and normal operation is expected to be 30% charge, a drive is selected at, perhaps, a 35% charge.
