## Ball Mill Operating Speed Mechanical Operations Solved

Ball Mill Critical Speed Ball mills have been successfully run at speedsbetween 60 and 90percent 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 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 ofcritical speed critical millspeedcritical speedleft is the speed at which the outer layer of media centrifuges against the wall secondcritical speedmiddle is the speed at which the second layer of media centrifuges inside the first layer nthcritical speed 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
