calculation for speed of ball mill of 21 rpm. 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.
Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. MTW Trapezium Mill. product description ： Bevel gear overall drive: traditional grinding mill is driven by speed reducer and coupling.
· If 75 percent of critical speed is considered desirable for efficient grinding in a meter (8 foot) diameter mill, then the same will be true for a meter (15½ foot) diameter mill.
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 ...

· Rotation Speed Calculation of Ball Mill Critical Speed_ When the ball mill cylinder is rotated, there is no relative slip between the grinding medium and the cylinder wall, and it just starts to run in a state of rotation with the cylinder of the mill. This instantaneous speed of the mill is as follows:
