how to calculate the ball mill 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
