The grinding media in a SAG mill are larger than in a ball mill, and there are fewer of them per ton of ore. The larger grinding media also contributes to a coarser grind, which is beneficial for downstream processes like flotation. SAG mills are typically operated at a constant speed, with the feed rate controlled by the mill weight.
According to Hassanzadeh [6], about 37% of the costs are used for grinding media only,13% for liners, and about 50% is used for energy in an industrial ball mill. This is evidence that media consumption has its fair share of the operating costs of the …

- In any mill, the rate at which the weight of any ball decrease is directly proportional to its weight.
- In any mill, the rate at which the diameter of a ball decreases is directly proportional to its diameter.
- In any mill, the rate at which the surface of any ball decreases is proportional to its surface.
- In any mill, the rate at which the weight of any ball decrease is directly proportional to its weight.
- In any mill, the rate at which the diameter of a ball decreases is directly proportional to its diameter.
- In any mill, the rate at which the surface of any ball decreases is proportional to its surface.
- Since the rate at which a ball loses weight varies as the work done upon it in the mill, it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball. This is se...
