In a highenergy ball mill, the rotary shaft is just like a cantilever beam and it rotates with the same velocity as the mill pot. The flexural stress on the bottom of the rotary shaft is higher and changes periodically. Too high an impact frequency will increase the stress of the rotary shaft and could cause a fatigue failure.
