s MSI/MPSI mills are ideal for grinding ore or primary crusher products. This line of mills includes models of various sizes and capacities Diameters from m to m A capacity of up to 28 MW Synchronous asynchronous (induction) and woundrotor motors With rolling or plain bearings (hydrodynamic or hydrostatic) Due to the fact that
An Autogenous Milling defined as used in this study the term Autogenous milling means a process in which the size of the constituent pieces of a supply of rock is reduced in a tumbling mill
semi autogenous grinding mill Online consultation Ask for quotation principle Product Parameters Browse other product principle Its main component is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded.
The semiautogenous mill can be equivalent to two or three stage crushing and screening rod mill and part or all of the ball mill grinding operation effect. SAG mill is also the best solution for wet grinding. In this regard the crushing and screening process is difficult to complete. Efficient Automated Operation
In a semiautogenous grinding (SAG) mill 50Jo to 10 of the mill volume may be occupied by grinding balls whereas a range of 25 to 45 is more usual in ball comminution of mineral ores using ""conventional"" techniques has been described in previous papers.

Five and one quarter inch steel grinding balls cannon balls occupy 8 of the mill volume and are consumed in the grinding action at the rate of 600 000 pounds per month. The SAG mill and all other grinding equipment is remotely monitored and controlled via computer from a central control room.
An autogenous mill of ID m and an effective grinding length of m was fed with ore of SG to 20 of its volume.. The mill was operated continuously 24 hours per day at 1200 t per day and 75 of the critical solids in the mill charge were at 80 solids.
SAG is an acronym for semiautogenous 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 () in diameter powered by a 28 MW (38 000 HP) motor.
This semiautogenous mill also called semiautogenous grinding mill or SAG mill is mainly used to grind ores and other particulate matter in different fields like chemical industry mining field metallurgy industry building material sector and so on. It is an autogenous mill in nature but it employs grinding balls to assist in its
Semiautogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diametertolength ratio of around two. With this high aspect ratio SAG mills generate both thrown and cascading ballmilling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
