  • critical speed - wikipedia

    critical speed equation. like vibrating strings and other elastic structures, shafts and beams can vibrate in different mode shapes, with corresponding natural frequencies. the first vibrational mode corresponds to the lowest natural frequency. higher modes of vibration correspond to higher natural frequencies.

  • ball mill critical speed - mineral processing and metallurgy

    the critical speed of a rotating mill is the rpm at which a grinding medium will begin to centrifuge, namely will start rotating with the mill and therefore cease to carry out useful work. 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. rod mills speed should be limited to a
