    · Intermediate Autogenous Grinding Autogenous grinding tests were run in a 10ft x 4ft Rockcyl mill The principle of prepared feed and media was utilized to determine how coarse a feed could be commercially fed to a rock mill Secondary rock milling was expanded toward the particle sizes of primary milling while still utilizing the practicesAutogenous 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 stagesAutogenous grinding mills (AG mills) minevik Outotec· Autogenous Mill Types There are basically three general types of autogenous grinding mills: a Primary autogenous mills which process directly the total discharge of primary crushers (usually set at 6″ to 10″ open side setting) Under some circumstances and for certain types of ore, small ball charges (usually less than 5% of the millAutogenous Grinding & Semi Autogenous Grinding
