SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill
Mines (WA) 36ft SAG mill the number of Outer Head Liners was reduced from 36 to 18 pieces and in doing so reduced the time to replace them by 9 hours at a cost downtime saving of about U$25,000 per hour. In this case the liners sections are 3.5 t each. For smaller mills the liners have to be handled and installed manually, so smaller blocks with
In DR-Congo, Kipushi Concentrator has one 18'diam X 6'L Hardinge Cascade-Mill running in the range of 1500-2000 tpd as FAG Mill (design not allowing the use of balls) assisted by: - one Ball Mill before 1992 to treat Cu-Zn sulphide ore by differential flotation; - and 2 Ball Mills from 1998 to make Cu-Co oxide ore flotation.
The South African style SAG (RoM) mills operate in a window that is almost exclusive from the operation of the Australian and North American mills that have been used for the development of SAG mill models.

SAG mills of comparable size but containing say 10% ball charge (in addition to the rocks), normally operate between 70 to 75% of the critical speed. Dry Aerofall mills are run at about 85% of the critical speed. The breakage of particles depends on the speed of rotation.
The improved liner life has been extended by 1500 h, and the metal scrap rate has been reduced from 47 to 30 % [12, 13]. M. Yahyaei and M. Maleki-Moghaddam used GMT (Grinding Media Trajectory) software to simulate the motion of the medium in the SAG mill, modified the equation of the trajectory of particles in the mill, and improved the liner ...
