Read MoreAug 01 2004 In this study it was found that optimum grinding occurs at 85 of critical speed compared to the optimum grinding at 70 of critical speed of the ball mill in the cement factory. The variation of a T values with the fraction of mill critical speed φ c gave high correlation coefficients of 0.98 and 0.96 for clinker and limestone .
Read MoreRod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind a rod mill uses less steel than a ball mill because of the lower speed and better contact between .

Effect of mill speed on the energy input in this experiment the overall motion of the assembly of 62 balls of two different sizes was studied the mill was rotated at 50 62 75 and 90 of the critical 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 .
Read MoreJun 19 2015 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.

Read MoreThe Critical Speed for a grinding mill is defined as the rotational 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. Result 2 This mills .
