Ball Mill Operating Speed - Mechanical Operations Solved ,

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
