SAG mill diameter inside liners = 12.024 m (40 ft, 3.3 inch effective liner thickness) SAG mill effective grinding length = 6.072 m (19.9 ft). The paper erroneously says belly length is 22 ft in Table 2.
A SAG mill is characterized by its large diameter and short length. It rotates, tumbling its contents violently , causing a breaking action. The mill is lined with wear resistant steel liners which are fitted with lifters to assist with raising the load.
Enter the width of a mill shell liner. Note this is not the width of a lifter You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width.

The charge level of a mill can be described as the volume occupied by the . is to increase in smaller diameter mills, which is the case of the measured ball mill. Get Price SAG Mill Circuit zenith
TECHNICAL NOTES 8 GRINDING R. P. King. 82 amp;ROOLVLRQ amp; is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg LG A mill power equation for SAG mills. Minerals and Metallurgical Processing. Feb 1990 pp5762.
A SAG mill is generally used as a primary or first stage grinding solution. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. SAG mills are primarily used at gold, copper and platinum mines with applications also in
Aug 25, 20140183;32;5 It is possible to increase the diameter of SAG but now there is no need. SAG of 12 meters and 20% ball charge can be achieved capacity up to 10000 t/h. Hvan Alexander, Uzbekistan. Reply Delete. Where are SAG mills going? Two major conferences just a week away;
SAG Mill Operation at Cortez Evolution of Liner Design from Current to Future Operations Julius Stieger1, Process Superintendent Dave Plummer2, The SAG mill is 26 diameter x 123 EGL and powered by 4,500 HP motor driven by a variable
by volume load. Recent studies in the threefoot diameter SAG mill are instructive. The following graph shows the relevant facts as Figure 2. Figure 2 Pilot Plant kg/hr Vs Charge % by Volume This data is indicative of trends that were happening in the 3ft. diameter SAG pilot mill. They have not been proven in large commercial scale mills.
Now, lets suppose you have a SAG Mill and Ball Mill that are not drawing full kW Power. The SAG Mill has a small circulation load of oversize given be the 3/8 trommel screen and the 1/2 x 1 1/4 discharge grates.
SAG is an acronym for SemiAutogenous Grinding. SAG mills are autogenous mills but 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 diameter, powered by a 28 MW (38,000 HP) motor.
