— 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, (displaystyle n_c = frac{1}{2pi}sqrt{frac{g}{R-r}} ) where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30 ...
