The grinding media can be classified into glass beads, ceramic beads (including zirconium silicate beads, zirconium dioxide beads, aluminum dioxide beads, rare earth metal-stabilized zirconium dioxide beads, etc.), steel beads, and the like, depending on the material.

The size of the grinding beads determines the number of contact points between the grinding beads and the material, and the more the beads with small particle size are contacted in the same volume, the higher the grinding efficiency theoretically is; on the other hand, when milling relatively large sized material, such as 100 micron slurry, beads with D ═ 1mm are not favored because the small beads do not have sufficient energy to be milled and dispersed, and larger size beads should be used.

The process that the material was milling along with the reduction of material diameter, should match the less ball of milling of diameter, and traditional sand mill is mostly the single-stage sanding, and its efficiency of milling is lower, can't realize milling different particle size's material.
