Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to 1.5. As the name implies, the grinding media in these mills are steel balls.
Ball mills are commonly used in the manufacture of Portland ore and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor,  drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption ).
