The critical speed of a SAG mill is the speed in RPMs at which centrifugal force causes the material being ground to be held against the inside of the shell. This speed is only dependent on the ...
Aug 03, 1999018332Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method DEM. The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter. The results of the present work ...

critical, a variable speed drive is recommended. This permits the operator to control his mill speed to suit. Most mills rotate at 60 to 65 percent of critical speed Nc. This formulation is for wet milling where as dry milling needs to be adjusted by 2 to 5 RPM faster. These speeds hold true for any media regardless of shape for density.
The appendix of the paper lists the mill speed as 12.5 RPM. The mill is fixed speed, so the critical speed is only a function of mill effective diameter as liners wear. Doing the math neglecting the balls gives a 68.4 critical speed. The ball mill belly length can be achieved with a 18 degree head angle and 1.9 m trunnion diameter.
