Autogenous Grinding Semi Autogenous Grinding Circuits

20/07/2017  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 mill volume, but sometimes up to 10%) may be used with advantage to complement the natural rock grinding media forming inside the mills.

AG SAG Mill for Mineral Processing Wet Aerofall SAG ...

AG mill (autogenous mill) is a medium-free mineral grinding equipment. The raw ore and the coarsely crushed ore are directly fed into the AG mill. No other medium is involved in grinding. Only the impact between the ore is used for self-grinding. The ore larger than 100mm in the AG mill plays the role of grinding medium. When the AG mill operation is started, the ore is directly self grinding.

Factors Affecting Ball Mill Grinding Efficiency

25/10/2017  For example, Turner (1979) has demonstrated an overall increase in capacity of almost 800 percent by ball addition to an ore of extreme difficulty to grind in the autogenous mode, and attributes the increased efficiency to both (a) impact action of the balls, and (b) increased usage of abrasion forces on greater surface area created by (a). The same source of synergy found in Turner’s “optimized load” principle can also be applied to ball
