The SAG mill has a mill diameter of 24 ft (73 m) and an effective grinding length of 185 ft and a structural charge mass of 315 t, Condor Gold said The structural design ball charge is 11% with a structural design load volume of 35%GRINDING: Outotec builds world’s largest SAG mill FINLAND – At 122 metres diameter and 88 metres long, the new semiautogenous mill that Outotec is building may well be the largest SAG mill in the world The huge mill will offer increased efficiency, effective grinding conditions, 15%GRINDING: Outotec builds world's largest SAG mill The SAG mill (AG mill) has a large diameter and a small length It looks like a flat round drum The diameter of the SAG mill is generally about three times its length The diameter of the hollow pivots at both ends of the barrel of a SAG mill is large This SAG mill design can facilitate largesized materials to enter the barrel smoothlyAG SAG Mill for Mineral Processing Wet Aerofall

Semiautogenous grinding (SAG) mill liner design and

mill is equal to twice the number of the feet in the mill shell diameter (eg, a 34ftdiameter mill shell would have 68 shell lifters) This is also called a 2D shell lining Eliminating some shell lifters increases the volume of charge between the lifters (“the bucket”) and the total charge that should be lifted in each rotation of the mill, hence potentially increasing the milling actionSAG mills use a ball charge of 8 to 21% The largest SAG mill is 42′ (128m) in diameter, powered by a 28 MW (38,000 HP) motor A SAG mill with a 44′ (134m) diameter and a power of 35 MW (47,000 HP) has been designed Attrition between grinding balls and What is the difference between a SAG mill and ball mill? SAG mill vs Ball mill Crushing ratio The biggest characteristic of the sag mill is that the crushing ratio is large The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 01 mmWhat's the Difference Between SAG Mill and Ball Mill
