THE OPTIMAL BALL DIAMETER IN A MILL. The optimal ball diameter in a mill 333 The grinding efficiency of the narrow particle size fractions with ball charge of various diameters has been observed through the constant of milling rate k in the equation of the grinding kinetics law for the first order grinding R R 0 . 7/24 Online. Effect of ball and feed particle size distribution on the . In this ...
