Cast Grinding Steel Balls

The lower impact forces are due to a combination of both smaller ball masses and lower drop heights resulting from the use of smaller balls and smaller mill diameters, respectively. The feed ore in primary grinding mills is typically very abrasive owing to its particle size, shape, and mineralogy.

Studies on Scale-Up of Ball Mills | SpringerLink

Data from ball mills with a wide range of diameters are analyzed using detailed mathematical/numerical models. Analysis shows the relative power inefficiency of large ball mills is due to their inefficient breakage of coarse particles. The models developed can be used to scale-up mill behavior. The behavior of large mills at Bougainville and Pinto Valley is compared. It is concluded that the ...
