Ball Mill Operating Speed - Mechanical Operations Solved ...
2021-4-22 The 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 of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.

Determining the Coefficient of Friction
2013-10-2 If you have an object moving at some velocity v and you let it roll or slide along a surface until it stopped. You could then measure the time t it takes to stop to determine its coefficient of friction. From the Force Equation, F = m*a, where a is the acceleration. Since the object is starting at some velocity v and decelerating until v = 0,
