Ball Mill Critical Speed Mineral Processing Amp Metallurgy

ball mill critical speed is the speed at which the centrifugal forces equal gravitational forces at the mill shells 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 rotation is usually between to revolutions per minute, depending upon the diameter of the mill. the larger the diameter, the slower the rotation. 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.
