2009-10-1  The grinding mechanisms are related to the movement of the grinding media in the grinding chamber. Cleavage and abrasion of particles are the result of compression forces and shear in the centrifuged packed bed of grinding beads.

2004-11-1  Mathematical characterization of impact breakage as a mechanism for grinding media consumption In operations where noticeable ball breakage is to be expected—like in high-impact, semiautogenous grinding (SAG) applications—an expanded, conceptual model, based on pilot Drop Ball Testing (DBT) results has been proposed to incorporate breakage as a potentially significant grinding media consumption mechanism.

The results showed that the initial reduction reaction temperature was significantly lowered by using the wet-grinding method. Even more remarkably, the maximum reaction rate increased from 62% to 157% when organic solvent was added to the mixture during the wet-grinding process and the proportion of decreased activation energy increased from 15.34% to 22.35%, as compared with dry-blending.
