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 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
The L/D ratios of ball mills range from slightly less than 1:1 to something greater than 2:1. The tube and compartment ball mills commonly used in the cement industry have L/D ratios 2.75:1 or more. The fraction of critical speed that the mill turns depends on the application, and most mills operate at around 75% of critical speed.
Mill Speed Critical Speed. Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.

When the rotating speed of ball mill grinder is high, the height the ball raised is high now only the calculation formula on critical speed in theory is widely used. Read more Rod and ball mills circuit sizing method The Cement Grinding Office
The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Calculation Backup: the formula used for Critical Speed is: N c =76.6(D-0.5) where, N c is the critical speed,in revolutions per minute, D is the mill effective inside diameter, in feet. source: SME Mineral Processing Handbook, Page 3C-4.

critical speed of the ball millbraaijacks. A Ball Mill grinds material by rotating a cylinder with steel or ceramic grinding balls causing the balls to fall back into the cylinder and onto the material to be ground. Ball Mills have been successfully run at speeds between 60 and 90 percent of critical speed.
Mill Critical Speed Calculation. Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of the critical speed. Six lifter bars of rectangular cross-section were used at equal spacing.
