Mills Grinding Generally ball mills are more common than Rod mills or Sag Mills, there are other types of mills available such as Vertical mills but the last three mentioned are by far the most common. Ball and mills use steel balls or ceramic balls as their grinding media. Rods mills as the name suggest use rods as their grinding media. The larger mills are a continuous process which means ...

Among the different grinding processes, Autogenous (AG) and SemiAutogenous (SAG) mills are widely used for ore size reduction. The main difference between these two mills is the use of steel balls as grinding media, typically in the order of 612% in volume (Sbarbaro et al., 2005), in the SAG mills. With the addition of grinding media, the ...
