8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & 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 (8.2) The particle will remain against the wall if these two forces are in balance ie.
Alternatively it is argued that throughput via the SAG mill can be simply increased by selecting a larger transfer size.3 8.1 Ball mill specific energy kWh/t 9.9mm to 3. the T80 is a symptom of AG/SAG mill performance (throughput) not the cause.1 5.3 4.5 Despite the evidence against the use of the T80 in AG/SAG/ball mill circuit design.1 1 10 ...

The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.
Further work was followed up to optimize the 40 ft SAG mill size with the results showing that a slightly more expensive 42 ft SAG mill with equivalent power to the 40 ft SAG mill …
The Intelligent Mill Liner Bolt. Up until now, SAG mill operations have lacked the means to intelligently determine mill liner replacements, other than the "blind" option of shutting down production, clearing the feed chute and doing a full, physical inspection of the mill lining and its wear depth.

Basically, a SAG mill is a rotating cylindrical container that relies primarily on the tumbling action of chunks of ore to grind each other down to the size of coarse gravel.
mill grinding balls / sag mill ball Introduction of Ball Mill Ball mill can triturate wet or all kinds hard grade of ore and other material, especially can make many sizes sands.
In a typical SAG mill, best practise is to utilise an array of iBolts spread out over the known high-wear areas on the shell and feed head, so as to ensure capture of the broad and singular wear events.
