Causality - Wikipedia. Causality (also referred to as causation, or cause and effect) is what connects one process (the cause) with another process or state (the effect),  where the first is partly responsible for the second, and the second is partly dependent on the first.
The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50% to 95% of the critical speed. The faster the mill speed, the greater the wear on the rods and liners.

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.
Effect of Mill Speed on the Energy Input. In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of the critical speed.

Ball Mills Our combined experience in ball mill design and process equipment development totals more than 60 years and allows us to put a unique spin on steel and lined mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's.
