Mill Critical Speed Formula Derivation (2 replies) In practice Ball Mills are driven at a speed of 50-90% 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 (i.e kWht -1) when the mill is operated above about 40-50% of the critical speed.

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 shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell.

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.

Ball Mill Critical Speed Mineral Processing & Metallurgy. A Ball Mill Critical Speed (actually ball, rod, The Formula derivation ends up as follow: Critical Speed is: N c =76.6(D 0.5) where: N c is the critical speed,in revolutions per minute, D is the mill effective inside diameter, in feet.
