DESIGN AND ANALYSIS OF BALL MILL INLET CHUTE FOR

Critical speed is the speed at which the centrifugal force is equal to the gravitational force. Normal mill speed is 70 to 80 of the critical speed Fig 1.3. For example if the critical speed is 18 rpm mill speed will be 15 rpm. If your mill speed is more than the critical speed and the centrifugal action

Mill Critical Speed Determination

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 shells inside surface. This is the rotational speed where balls will not fall away from the mills shell. Result 1 This mill would need to spin at RPM to be at 100 critical speed.

Ball mills are normally operated at around 75 of critical speed so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers although this depends upon feed input size mills including a roller press are mostly single-chambered allowing the use of different sizes of grinding media.
