Ball Mill Critical Speed Mineral Processing Metallurgy

Ball Mill Critical Speed Mineral Processing Metallurgy A ball mill critical speed actually ball rod ag or sag is thespeed 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 Sagmillingcom Mill Critical Speed Determination The "critical speed" for a grinding mill is defined as therotational speed where centrifugal forces equal gravitational forces at the mill shells inside surface this is the rotational speed where balls will not fall away from the mills shell result 1 this mill would need to spin at rpm to be at 100 critical speed Mill Speed Critical Speed Paul O Abbe In most cases the ideal mill speed will have the media tumbling from the top of the pile the shoulder to the bottom the toe with many impacts along the way the ideal mill speed is usually somewhere between 55 to 75 of critical speed critical mill speed critical speed left is thespeed at which the outer layer of media centrifuges against the wall second critical speed middle is the speed at which
