Ball mill basic design principles.
Ball mill critical speed mineral processing metallurgyA 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.
Ball mill are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 micronsTo achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced.
