Ball Mill Operating Speed Mechanical Operations Solved

the critical speed of ball mill is given by, where radius of ball mill; radius of ball. for 1000 mm and mm, 30.7 rpm. but the mill is operated at a speed of rpm. therefore, the mill is operated at 100 1530.7 48.86 of critical speed.effect of mill speed on the energy input In this experiment the overall motion of the assembly of balls of two different sizes was studied. the mill was rotated at 50, 62, and 90% of the critical speed. six lifter bars of rectangular cross-section were used at equal spacing. the overall motion of the balls at the end of five revolutions is shown in figure As can be seen from the ball mill critical speed derivation ball mills mine engineercom ball mill critical speed derivation,if the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill the point where the mill becomes a centrifuge is called the critical speed, and dragthe second is air drag, which.
