Ball Mill
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. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

What's the Difference Between SAG Mill and Ball Mill
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s

MEI's Barry Wills: The impact of milling costs on total mine operating
It has been shown, for example, that the replacement of a SAG mill with a HPGR in a conventional SAG-ball circuit may reduce grinding energy consumption by 15–20%. Taking into account additional savings, such as media and liner wear, it was found that a grinding cost saving of 25–35% was potentially achievable with the use of HPGRs in such conventional circuits.
