• ### TECHNICAL NOTES 8 GRINDING R. P. King

Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power

So to maximize the power coefficient the rotor’s aspect ratio should be as small as possible. As aspect ratio diminishes there are two advantages: the local Reynolds number rises and simultaneously the rotational velocity diminishes.

• ### How to Calculate Power Based on Force and Speed

In physics you can calculate power based on force and speed. Because work equals force times distance you can write the equation for power the following way assuming that the force acts along the direction of travel: where s is the distance traveled. However the object’s speed v is just s divided by t so the equation breaks down to.
