    Centrifugation is the process of spinning a mixture in order to separate out its components. For starters, centrifugation depends upon a centrifuge, which is a machine that spins, for this process

  • Ball Mills Mine Engineer.Com

    If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.
