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. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore,Grinding Machines: Types and Selection Principles,22.09.2020· The autogenous mill uses the ore itself as the grinding medium, which saves a lot of grinding balls and avoids product pollution. The feed size is 250~350mm. After one grinding, the product size is between several millimeters and 50μm. The autogenous mill has a large crushing ratio, which can replace medium and fine crushing operations and the first stage of grinding operations,(PDF) Design of a typical Autogenous Mill: Part-II,23.12.2013· The two main character of an Autogenous Mill e.g. size reduction which occurs through the detachment of material from the surface of larger particles (referred to as 'abrasion') and the grinding,US3404846A - Autogenous grinding mill - Google Patents,AUTOGENOUS GRINDING MILL Original Filed Oct. 9, 1962 8 Sheets-Sheet 2 a E i i a FIG. 3: IN VENTOR5.
