SAGMILLINGCOM : Mill Critical Speed Determination

Mill Critical Speed Determination The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface This is the rotational speed where balls will not fall away from the mill's shellBall Mills - Mine EngineerCom,The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 micronscritical speed for a ballmill - versionsolutions,critical speed for a ballmill Mill size – grinding economies of scale Relative lifecycle cost Lower power consumption Robust design Avoiding critical open gear power trains Variable speed Aluminium (EHC 194, 1997) - IPCS INCHEM
