Compared with other grinding media, the specific gravity of zirconia beads is relatively high, especially the 95 zirconia beads with high zirconia content, in which the zirconia content is as high as 95%, the specific gravity is 6.0g/cm3, and the bulk specific gravity is 3.6.

The more important parameters of zirconium beads are specific gravity and density. There are different parameters for zirconium beads with different particle sizes and types. Even for zirconium beads with the same particle size and types, different manufacturers also have different technologies. In this way, the quality of zirconium beads produced is also different. Since the filling in the sand mill is in volume, but the purchase of zirconium beads is in kg / T, we need to know what the relevant parameters mean and the conversion method.
Specific gravity and density of zirconium beads
Definition of specific gravity and density of zirconium beads
Specific gravity: also known as relative density. The specific gravity of solid and liquid is the ratio of the density of the material (fully dense state) to the density of pure H2O (999.972 kg / m3) at standard atmospheric pressure and 3.98 ℃.
The unit of specific gravity is g / cm3, kg / m3.
Density: mass per unit volume of zirconium bead.
The unit of density is g / cm3, kg / m3.
For liquid and solid values: specific gravity = density / 1000 (at this time, the density unit is kg / m3), but the specific gravity has no unit.
For gas: numerical value: specific gravity = 22.4 * density / 29 (at this time, the density unit is g / L), but the specific gravity has no unit.
Definition summary: zirconium beads are solid, so there is no difference in the values of specific gravity and density.
Pile specific gravity: the weight per unit volume of a pile of normally stacked materials (including the volume of voids between materials), that is, the average density of materials when they are naturally stacked. Therefore, the bulk specific gravity is calculated into the volume of material gap.
We take the Zeno yttrium stabilized zirconia beads (95 zirconium beads) of czy60 as an example, the specific gravity parameter is 6.0 and the bulk specific gravity is 3.6; Generally, the bulk specific gravity is used, because there is a gap in the middle of zirconium beads, so a cubic yttrium stabilized zirconia bead is 3.6 tons.
