What Itis The Optimun Speed For A Ball Mill

Oct 19, 2006 · Optimum RPM= .65 x Critical speed (cascading action of the media stops) Critical speed = 265.45/sqrt (Jar I.D. - Media O.D.) with dimensions in inches

Variables In Ball Mill Operation Paul O Abbe

Critical speed (CS) is the speed at which the grinding media will centrifuge against the wall of the cylinder. Obviously no milling will occur when the media is pinned against the cylinder so operating speed will be some percentage of the CS. The formula for critical speed is CS = 1/2π √(g/(R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. …
