The ball mill accepts the SAG or AG mill product. Ball 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 5–10 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.

For any process, including ball mill circuits, we can say that output equals input multiplied by efficiency*. Output = Input x Efficiency In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies.

• In case of continuously operated ball mill, the material to be ground is fed from the left through a 60o cone and the product is discharged through a 30o cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to the feed), from near the top of the shell. In doing so, the solid particles in between the

Method of balls rolling on ball- rolling mills is one of the most modern production methods. Transversal rolling of balls from the round billet is economical. It differs from other methods due to the possibility to produce grinding balls on the uninterrupted automated aggregates, which allows 2 to 8 times to increase the output and 10-15% to reduce the consumption of metal.
