mill speed critical speed paul o. abbe. mill speed critical speed. mill speed . no matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation
ball mill critical speed mineral processing metall. 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 maximum of 70 of critical speed and preferably should be in the 60 to 68 percent critical speed range
because you want the grinding balls to experience a free-fall motion, i.e. cataracting motion, i would recommend you consider a rotational speed between 65 and 85 of the critical speed of the mill
rotational speed for ball mill. critical rotation speed of dry ballmill was studied by experiments and by numerical simulation using discrete element method dem the results carried out by both methods showed good agreement it has been commonly accepted that the critical rotation speed is a function of a ball critical rotational speed ball
ball mill critical speed mineral processing amp metallurgy. 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
