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, respectively, through a regression analysis.
CRITICAL SPEED OF THE BALL MILL. Let a grinding ball of mass m is in motion in a mill of diameter D meters. It is at a position making an angle a at the center (called the angle of repose). The force acting on the ball are described in the figure. The centripetal force acting along C. The force of gravity due to its weight along G; The resultant force along P; The centripetal force is C. The ...

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 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.

The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the 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 ...
