autogenous amp; semi autogenous grinding circuitssemi autogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. figure 2 shows a typical conventional crushing grinding circuit with three stages of crushing followed by ball mills or rod mill ball mill combination.

autogenous mills, semi autogenous mills and ball mills for with this type of drive, the mill shell is driven via one or two pinions which transmit the motor power to the mill shell. ring gear and pinion are usu ally of the helical type. lubri cation is effected through a greasing system. the operat ing conditions can be moni tored by infrared devices.

ag autogenous grinding mineral processing amp; metallurgyintermediate autogenous grinding. a reasonable rate ratio between media and total mill feed was established. this ratio is dependent upon the quality of the media and the grindability of the mill feed. with a proper size ratio of media to feed, critical size buildup did not occur.

effects lead autogenous mill application

mill (grinding) 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

autogenous and semi autogenous mills metsoag/sag mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. because of the range of mill sizes available, ag/sag milling can often be accomplished with fewer lines than in a conventional rod mill ball
