18/07/2021· The image above represents critical mill of speed. To compute for critical mill of speed, two essential parameters are needed and these parameters are Mill Diameter and Diameter of Balls . The formula for
This formula calculates the critical speed of any ball mill. Most ball mills operate most efficiently between 65 and 75 of their critical speed. Photo of a 10 Ft diameter by 32 Ft long ball mill in a Cement Plant. Photo of a series of ball mills in
15/10/2015· In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of
19/06/2015· Critical speed is C.S. = 76.63 / 11^0.5 = 23.1 rpm Ball and SAG Mills are driven in practice at a speed corresponding to 60 81% of the critical speed, the choice of speed being influenced by economical considerations. Within that range the power is nearly proportional to the speed. Mill rotating speed impacts grinding rates.
