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%.67 The largest SAG mill is 42 (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.8
The primary function of Ball, Pebble and SAG mills is to grind, crush or mix materials into a finer grade of quality as required. Often the use of mill grinding acts as the stepping stone to larger processes which heavily depend upon the refinement of materials or physics related reactions induced by grinding and crushing.
Jun 06, 2016 By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling while convenient, this has the ...
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 redfastest, blueslowest moving particles image (135-6
You may find more information regarding the SAG discharge if you search them as scats (broken ball chips). Safety Notes they result from internal stresses in the balls impact and heat energy in the SAG mill causing a Martensite transformation in the ball (Crystals form in the metal) and they have a potential to rupture with very sharp edges.
The SAG mill specific energy consumption (E SAG) is calculated using the 1979 Barratt equation and the ball mill specific energy consumption (E bm) This model includes a phantom cyclone effect in the equations due to the ball mill being calculated by difference and not being calculated by the normal Bond equation.
3.5.2.2 Ball Mills. The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but
This is because the steel balls in the sag mill do the duty of . the larger rocks. As a result the more balls that are loaded into the sag ... HPGRs, AG/SAG mills and ball mills within ...

The results showed that the HPGR-ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG-ball mill circuit at the same P80 grind size of 160 mircons (m). At a grind of 80% passing 75 m, the HPGR-stirred mill circuit showed a 34% reduction in energy compared to the base case.
The two installed mills include a semi-autogenous (SAG) mill measuring 10.4 x 6.1 m with a drive output of 15 MW and a ball mill rated at 18 MW. The SAG mill reduces ore fragments with a maximum size of 250 mm (P80 152 mm) down to 2 mm, and the ball mill reduces the SAG mill product to about 74 m. Grinding is followed by flotation.
Feb 09, 2010 Otherwise you are trying to make you ball mill act as a SAG mill. SAG mill comminution can take these large particles. Its breakage evolution is done at the base (toe) of the mill where the ore kidney changes direction near the toe of the charge. More than 95% of the rock is broken in the lower kidney section where pressure is maximized between ...
