Read MoreThe balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size. the large balls tend to break down the coarse feed materials and the smaller balls help to form he fine product by reducing void spaces between the balls. ball
Read MoreBall mills give a controlled final grind and produce flotation feed of a uniform size. ball mills tumble iron or steel balls with the ore. the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills dry basis is typically 75 vol. ore and 25 steel.
