Mill Critical Speed Formula Derivation 2 replies In practice Ball Mills are driven at a speed of 5090 of the critical speed the factor being influenced by economic consideration Mill capacity can be increased by increasing speed but there is very little increase in efficiency ie kWht 1 when the mill is operated above about 4050 of the critical speed AMIT 135 Lesson 7 Ball Mills Circuits

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 Chat Here Mill Critical Speed Calculation If 75 percent of critical speed is considered

Many practical applications suggest as good practice that the maximum operating speed should not exceed 75% of the critical speed however there are cases that require speeds above the critical speed to work correctly In such cases it is important to accelerate the shaft through the first natural frequency quickly so that large deflections don't develop

Derivation Of Critical Speed Of Ball Mill Jun 6 1993 lays the foundation for the derivation of a model if a large the mill speed nears 100 per cent of critical speed centrifug ing of the outer bonds equation implies that torque is zero for all j at for ball mill grinding control read

The critical rotation speed of the jar significantly depends on the ball-containing fraction as seen in Fig 3 and is not determined by Eq (1)for given radii of the jar and the ball only The critical rotation speed is close to the value determined by Eq
