How to calculate critical speed in circular motion

Apr 14, 2012· In one textbook, it says that the critical speed is the minimum speed at which an object can complete the circular motion It gives the formula: v = square root of (g*r) However, in another textbook it says that the formula is: v = square root of (2*g*r) How can there be two different types of.

Page 1 Ball Milling Theory

Page 1 Ball Milling Theory Introduction: Figure 1: Ball milling terminology I was first given the formula for gunpowder by my Uncle at age 14, after he had observed my apparent obsession with class C fireworks Being a scientist who had experimented with the ancient recipe , Critical Speed (RPM) Optimal Speed (RPM) of the media being used.

Ball Mill Operating Speed

At what speed will the mill have to be run if the 100 mm balls are replaced by 50 mm balls, all the other conditions remaining the same? Calculations: 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 = 307 rpm But the mill is operated at a speed of 15 rpm.
