critical speed of hammer mill with examples

Ball mills have been successfully run at speeds between60and90 percentof critical speed, but most mills operate at speeds between65and79 percentof critical speed. Rod mills speed should be limited to a maximum of70% of critical speed and preferably should be in the60 to 68 percentcritical speed range.
