Calculation of Tip Speed
The tip speed of the mixer's agitator - sometimes also called mixing tool - can be calculate the following way
Equation 1 : Tip Speed calculation
Why calculation the tip speed ?
The tip speed of the mixer is a very important data to determine the mixing regime thanks to the Froude Number but also to verify that the agitator speed is not exceeding 1 m/s whenever the mixture in its explosivity range (ATEX), typically when loading and discharging the mixer. The mixer speed in rpm at which the tip speed equals 1 m/s is called the ATEX speed of the mixer.
