## Mill Critical Speed Calculation

Ball Mill Critical Speed Mineral Processing Metallurgy Ball mills have been successfully run at speeds between60and90 percentof critical speed but most mills operate at speeds between65and79 percentof critical speed rod mills speed should be limited to a maximum of70 of critical speed and preferably should be in the60 to 68percent critical speed range Mill Critical Speed Calculation Effect ofmill speedon the energy input in this experiment the overall motion of the assembly of 62 balls of two different sizes was studied themillwas rotated at 50 62 75 and 90 of thecritical speed six lifter bars of rectangular crosssection were used at equal spacing the overall motion of the balls at the end of five revolutions is shown in figure 4 as can be seen from the Ball Mill Design Critical Speed Formula Provesprojektde Ball mill design critical speed formula aug rotationspeedcalculation ofball mill critical speedwhen theball millcylinder is rotated there is no relative slip between the grinding medium and the cylinder wall and it just starts to run in a state of rotation with the cylinder of themillthis instantaneousspeedof themillis as follows Ball Mill Operating Speed Mechanical Operations Solved At whatspeedwill themillhave to be run if the 100 mm balls are replaced by 50 mm balls all the other conditions remaining the same calculations thecritical speedofball millis given by where r radius ofball mill r radius ofball for r 1000 mm and r 50 mm n c 307 rpm but themillis operated at aspeedof 15 rpm Sagmillingcom Mill Critical Speed Determination Result 1 thismillwould need to spin at rpm to be at 100critical speed result 2 thismillsmeasured rpm is ofcritical speed calculation backup theformulaused forcritical speedis n c 766d05 where n c is thecritical speedin revolutions per minute
