Ball Mill Critical Speed Mineral Processing

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 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 can be seen from the Mill Critical Speed CalculationBall Mill Critical Speed Derivation Ball Mill Critical Speed 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 shells 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 variesThery Of Critical Speed Of Ball Mill

Question On Critical Speed Of Ball Mill

The Critical Speed is used for the determination of ball mill ideal operating speed But for comparison rod mills would operate between 50 to 95 of the critical speed The faster the mill speed the greater the wear on the rods and linersMill Speed Critical Speed Mill Speed No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation Too low a speed and little energy is imparted on the productMill Speed Critical Speed Paul O AbbeThe "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 : Mill Critical Speed

Calculations: The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball For R = 1000 mm and r = 50 mm, n c = 307 rpm But the mill is operated at a speed of 15 rpmBall Mill Operating Speed Mechanical
