#### Mill Critical Speed Calculation

The speed of the mill was kept at 63% of the critical speed. The face angle was varied from 90 to 111 degrees for the three types of configuration 1, 2 and 4, as shown in the figure. Also, the height of the lifter bar in configuration 3 was changed to observe the trajectory.Ball Mill Critical Speed - Mineral Processing and MetallurgyRod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range. Pebble mills are usually run at speeds between 75 and 85 percent of critical speed. Ball Mill Critical Speed . The black dot in the imagery above represents the centre of gravity of the charge.SAGMILLING.COM .:. Mill Critical Speed DeterminationThe "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell& 39;s inside surface. This is the rotational speed where balls will not fall away from the mill& 39;s shell. Result 1: This mill would need to spin at RPM to be at 100% critical speed. Result 2: This mill& 39;s ...
