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 shells inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical

Live ChatWhat 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. In the other side of my shafts there are two 40 mm

Live ChatThe critical speed of ball mill is given by where R = radius of ball mill r = radius of ball. For R = 1000 mm and r = 50 mm n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed. If 100 mm dia balls are replaced by 50 mm dia balls and the other conditions

Live ChatImportant consideration for a ball end mill is feed rate. Along with that decreased surface speed toward the center goes increased chip load. Start your feed at half what you would use for a similar straight cutter in the same material at the same rpm.

In summary the larger the mill the slower you will want the RPM to be set at and the mill to turn. Ref. By David Michaud 201703
