When finer particle sizes are required, grinding or milling is employed. Milling makes use of a combination of impact, attrition, and shear mechanisms to further reduce the size of ore particles down to micron sized particles. There is a combination of these mechanisms in a mill, but depending on the mill, one or two mechanisms can be dominant.

Grinding Media: Unlike traditional ball mills, SAG mills use a combination of ore and steel balls as grinding media. The ore itself is used to break up the larger chunks of material, and steel balls are added to assist in further grinding. Charge: The combination of ore and steel balls inside the mill is referred to as the "charge." The ...

The BBMWI determines how much energy is needed to grind a sample of ore in a ball mill [22]. This measurement is expressed in kilowatthour per ton (kWh/t), which is the energy required to grind a ton of material. The BBMWI is used to design new grinding circuits and may also be used in the simulation and optimization of existing milling circuits.

Two ore samples were characterized, and benchscale grinding tests were carried out in laboratory mills 30 and 58 cm in diameter. The results indicated that coarse compact itabirite ore (pebbles) can be used as grinding media. Grinding tests have shown that replacing 25% of the steel balls with pebbles offered promising results.
