### Ball Mill Operating Speed MSubbu Academy

Calculations: The critical speed of ball mill is given by, n c = 1 2 π g R − r where R = radius of ball mill; r = radius of ball For R = 1000 mm and r = 50 mm, n c = 307 rpm But the mill is operated at a speed of 15 rpm Therefore, the mill is operated at 100 x 15/307 = 4886 % of critical speedThe formula for critical speed is CS = 1/2π √ (g/ (Rr) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media This reduced to CS = 26545/√ (Rr) Dry mills typically operate in the range of 50%70% of CS and most often between 60%65% of CSVariables in Ball Mill Operation Paul O Abbe® Bearing width of 20 mm and inner diameter of 55 mm and outer diameter of 75 mm against the speed of 343 rpm derived from the stage II speed reducer with static loading capacity of about 61 kNCalculation method and its application for energy
