what is critical speed of ball mill

    hosokawa-alpinede: SO - Super Orion Ball Mill- what is critical speed of ball mill ,Ball mills are usually operated at 75% of the critical speed, ie in the fringe area between cascading and free-fall With a specially designed frequency converter, it is even possible to operate a heavy ball mill at variable speedRod mills, how they function - Mine EngineerComThe Critical Speed is used for the determination of ball mill ideal operating speed But for comparison, rod mills would operate between 50% to 95% of the critical speed The faster the mill speed, the greater the wear on the rods and liners.
