Autogenous grinding mills (AG mills) - liming
Autogenous mills, or AG mills, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

SAG mills (semi-autogenous grinding mills) - liming
Semi-autogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
Autogenous Grinding - Mining Fundamentals
Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or porcelain balls are used as media.
Autogenous and Semi-Autogenous Mills | FLSmidth
Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge.

Jan 29, 2020 · Analyzing the operation and design of an autogenous mill using EDEM software in collaboration with Tega Industries. By Giorgos Antoniouon. 29 Jan 2020. A mill is a device that breaks solid materials into smaller pieces by grinding and crushing. Comminution is an important unit operation in many processes and there are many different types of mills for different types of materials processed.
Autogenous AG & SAG Mills for Sale
The autogenous mill itself is a coarse-grinding device, consisting of tumbling drum with a 25% to 40% volume filling of ore. Metallic or manufactured grinding media is not used. Autogenous mills are fed run-of-mine ore or primary crusher product that is <25 cm (10″). Inside the mill, large pieces break into smaller pieces a few inches in size.
