SAGMILLINGCOM : Mill Critical Speed DeterminationOptimum choice of the make-up ball sizes for maximum

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 shell1 Introduction The ball size is one of the critical factors for determining the mill performance of ball mills It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particl.
