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 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 TheoreticalGet Price
A ball mill is simply a container that is filled with pebbles either of porcelain or stones e.g. Flint into which a charge powder or slurry is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them. Ball mills can be continuous or periodic, they can be small or gigantic, low speed
