EF5BM=[ P80+10.3 1.145×P80] ( 3 ) The EF4 formula requires both the rod mill and ball mill work index (rod mill Wi is used to calculate the optimal feed size) and because this is a "single-stage ball mill" calculation, the F80 is actually the rod mill feed size (10,000 µm) from Table 1 and the P80 is the ball mill circuit product. The EF5 factor only applies …

The slurry transportation in AG/SAG mills is a two-stage process consisting of flow through the grate and the discharge of slurry by pulp lifters into the discharge trunnion. The grate-only discharge condition provides the ideal relation between slurry hold-up and flowrate. By attaching pulp lifters to the grate, the ideal hold-up–flowrate ...

The mine is closed and now you need to know how to put the SAG or Large Ball Mill in care and maintenance does not have to be complicated to the point where you need bridge erection equipment for lifting a Mill (AG/SAG/Rod/Ball). You actually need to lift a car higher than a mill. All you need to do is jack the mill up about 1/2″.

Ball Mills: Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with. the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG. mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder.

Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
