A ball mill 1.2 m in diameter contains 80 mm balls is being run at 160 rpm. does the mill work properly? why? if there will be a problem how can it be 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 30.7 rpm. but the mill is operated at a speed of 15 rpm.
