Get PriceBall mills have been successfully run at speeds between60and90 percentof critical speed, but most mills operate at speeds between65and79 percentof critical speed. Rod mills speed should be limited to a maximum of70% of critical speed and preferably should be in the60 to 68percent critical speed range.

Read MoreThe ideal mill speed is usually somewhere between55% to 75% of critical speed. Critical Mill Speed Critical Speed (left) is the speed at which the outer layer of media centrifuges against the wall.
Read MoreThe critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r =50 mm, n c =30.7 rpm. But the mill is operated at a speed of15 rpm.
Read MoreThe speed of the mill was kept at63% of the critical speed. The face angle was varied from90 to 111 degreesfor the three types of configuration 1, 2 and 4, as shown in the figure. Also, the height of the lifter bar in configuration 3 was changed to observe the trajectory.

Read MoreCritical rotation speedof 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 thecritical rotation speedis a function of aballradius and a jar diameter.
