Ball Mill Critical Speed Mineral Processing Metallurgy. A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell''s inside surface and no balls will fall from its position onto the shell.
The critical speed of the mill, c, is defined as the speed at which a single ball will just remain against the wall for a full cycle. At the top of the cycle =0 and Fc Fg () mp 2 cDm 2 mpg () c 2g Dm 1/2 () The critical speed is usually expressed in terms of the number of revolutions per second Nc c 2 1 2 2g Dm 1/2 (2×)1/2 ...

The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.
Oct 19, 2006· What it is the optimun speed for a ball mill ? posted in Pyrotechnics: I have done a ball mill, recenly finished, but the motor has too rpms, is too fast for use in a ball mill (the pvc cylinder that i use, left of the shafts). With the motor i will use a 40 mm pulley, because i have a 50 mm driven pulley, in one of my two shafts.
