    The "Critical Speed" for a grinding mill is defined as therotational speedwhere centrifugal forces equalgravitational forcesat the mill shell's inside surface. This is therotationalspeed 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.

    Ball Mill Operating Speed Mechanical Operations Solved

    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 = 30.7rpm.But the mill is operated at a speed of15 rpm.Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.
