# Mill Equation Derivation

• ### Physics of Wind Turbines Energy Fundamentals

Post mills appeared in Europe in the twelfth century To derive the above equation the following was assumed A 1 v 1 = A 2 v 2 = A v1 v2 / 2 We designate the ratio v2/v1 on the right side of the equation with x To find the value of x that gives the maximum value of C P we take the derivative with respect to x and set it to zero This gives a maximum when x = 1/3 Maximum drawing

• ### Mill Critical Speed

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 Result #1 This mill would need to spin at RPM to be at 100% critical speed Result #2 This mill s
