Thecritical speedcan also be derived by 42.3/D0.5 where D is the diameter in METRES. For instance, a 90cm diameterball millhas acritical speedof 44 rpm. For efficientmilling, thecritical speedis too high you need now to determine the optimalspeedwhich is about 70-75% of thecritical speed. For instance a 90cm diameterball mill...
Criticalrotationspeedof dryball-millwas studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that thecriticalrotationspeedis a function of aballradius and a jar diameter.
