2019 3 9 2019 3 9 The rotation is usually between 4 to 20 revolutions per minute depending upon the diameter of the mill This formula calculates the critical speed of any ball mill Most ball mills operate most efficiently between 65 and 75 of their critical speed heart outlined.

The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell s inside surface This is the rotational speed where balls will not fall away from the mill s shell Result #1 This mill would need to spin at RPM to be at 100 critical speed Result #2 This mill s

Critical rotation speed for ball milling

1999 8 3 1999 8 3 Critical rotation speed of dry ball mill was 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 the critical rotation speed is a function of a ball radius and a jar diameter The results of the present work
