Mill Speed Critical Speed Paul O Abbe

Ball Mill Critical Speed Mineral Processing Metallurgy 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 Ball Mill Operating Speed Mechanical Operations Solved Where r radius of ball mill r radius of ball for r 1000 mm and r 50 mm n c 307 rpm but the mill is operated at a speed of 15 rpm therefore the mill is operated at 100 x 15307 4886 of critical speed if 100 mm dia balls are replaced by 50 mm dia balls and the other conditions are remaining the same speed of ball mill 048862p x 98121 0025 05 148 rpm Mill Speed Critical Speed Paul O Abbe The ideal mill speed is usually somewherebetween 55 to 75 of critical speedcritical mill speed critical speed left is the speed at which the outer layer of media centrifuges against the wall second critical speed middle is the speed at which the second layer of media centrifuges inside the first layer nth critical speed right is the speed at which the nth layer of media centrifuges inside the n1 layer What It Is The Optimun Speed For A Ball Mill Oct 19 2006 congratulations on your ball mill youll want to further reduce your motor speed by 31 to mill more efficiently right now your rpm is just slightly under the speed where the media wont do any work the optimum speed for your jar to turn isaround 90 rpmlike frozentech said Ball Milloperatingspeed Mechanical Operations Solved The criticalspeedofball 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 therefore themillis operated at 100 x 15307 4886 of criticalspeed
