Analysis of ball mill grinding operation using mill An analysis of the published experimental data on variation of the mill power with mill speed shows that in the range 55–70% critical speed the torque corresponding to the net power drawn by the mill either remains practically constant, or it increases gradually with the mill speed by about 8% . These data can be utilized for evaluating the energy efficiency of the grinding operation. For
Chat OnlineThe effect of the fraction of mill critical speed (Oc) on the grinding for model parameter aT was found to be different for two different samples: aT=0.0344 exp(0.00301 Oc) for clinker and aT=0.0225 exp(0.06183 Oc) for limestone. Additionally, it was found in this study that optimum grinding occurs at Oc=85%, in contrast to the 70% of critical speed of the ball mill in the cement factory.
iran critical speed formula of cement ball mill. 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 [email protected] Send Message Get a Quote. critical speed

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being

SAGMILLING.COM .:. Mill Critical Speed Mill Critical Speed Determination. The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Mill Inside Diameter: Enter the mill diameter inside the shell (excluding liners). Most mill sizes are reported by

The mill was rotated at 50, 62, 75 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 4.
