Enter the measured mill rotation in revolutions per minute. Result #1 This mill would need to spin at RPM to be at 100% critical speed. Result #2 This mill's measured RPM is % of critical speed.

#### Effect of ball size and powder loading on the milling

However, reports on the efficient combinations of ball sizerotation speed have been sparse in the literature. Here we report that there exists an optimal ball size for efficient milling at a given rotation speed, based on a laboratory scale wet ball mill.

#### TheBackShed Wind speed and windmills explained.

Wind Speed and windmills explained These low speeds do not suit most alternators or generators and, in the case of the 20 meter turbine, would certainly require stepping up by a gearbox. This assumes that the turbine is 30% efficient. According to a Mr. Betz, you can actually only extract 60% of the wind energy anyway.

#### How do they measure the rotational speed of cricket balls?

$\begingroup$ A spin ball essentially changes direction and speed after its first hit on the pitch. I am writing this as a comment since I am not sure. Now, the change in speed and direction after the spin would somehow be related to the rotational axis and rotational speed.
