Cement Mill Critical Speeed And Effect Huaheng Org. The effect of mill speed on kinetic breakage . 1 8 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.
Get QuoteAug 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
Get QuoteThe "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. Result #1: This mill would need to spin at RPM to be at 100% critical speed. Result #2: This mill's
Get QuoteJun 19, 2015· A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula. The mill speed is typically defined as the percent of the Theoretical
Get QuoteThe 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.

Get QuoteJan 07, 2015· Raw mills usually operate at 72-74% critical speed and cement mills at 74-76%. 3.2 Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2*3.14*(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm. 7.
Get QuoteThe paper handle a few topics from cement industry, such are: critical speed, mill speed control. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back. Therefore, this application conceived a PID controller for control the mill speed, using Programmable Logic Controllers.
