    Ball Mill Critical Speed Mineral Processing Metallurgy

    Ball mills have been successfully run at speedsbetween 60 and 90 percentof critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range.

    Effect ofMill Speedon the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. Themillwas rotated at 50, 62, 75 and 90% of thecritical speed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the ...

    Mill Critical Speed Determination. The "Critical Speed" for a grinding mill is defined as therotational speedwhere centrifugal forces equal gravitational forces at the mill shell's inside surface. This is therotationalspeed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at 100% critical speed.

    Ball Mill Operating Speed Mechanical Operations Solved

    The 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 = 30.7rpm.But the mill is operated at a speed of 15rpm.Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.
