The Effect of Hammermill Screen Hole Diameter and Hammer ...

3,560 rpm, achieved by adjusting the VFD. Using these values, hammer tip speed was then calculated by multiplying π by the hammermill diameter (inches) and motor speed (rpm). This value was then divided by 12 to convert the hammer tip speed to feet per minute. Based on this formula and the measured motor speeds, the resulting hammer
