What are zirconia balls?

Zirconia balls are pearly and smooth beads that are an indispensable grinding tool. During the grinding process, the zirconia balls can make the ground objects finer. Moreover, zirconia balls have high specific gravity, high grinding efficiency, fine microstructure and better wear resistance, and are widely used by manufacturers.

Today, I am here to introduce the characteristics and types of zirconia balls to everyone.  

Characteristics of zirconia balls

1. High grinding efficiency: The specific gravity of 65 zirconia beads is twice that of glass beads, and the grinding efficiency is higher under the same conditions.

2. Good fluidity: the product has good roundness and smooth surface, and the wear on the equipment is lower than that of other grinding media.

3. Impact resistance and low wear: 65 zirconia beads have good toughness, no cracking or peeling in high-speed and high-concentration machines, and wear resistance is 30 times higher than glass beads.

4. Low cost: Selecting this product will definitely reduce the overall cost, such as medium wear, power consumption, labor, and equipment, and greatly improve product quality.

Classification of zirconia balls

At present, there are many classifications of zirconia balls, but only the following ones are suitable for grinding machines: yttrium-stabilized zirconia balls, cerium-stabilized zirconia balls, 80 zirconia beads and zirconium silicate beads.

Yttria Stabilized Zirconia Balls/Beads

The zirconia content of this product is nearly 95%, so it is often called "95 zirconia" or "pure zirconia beads". It uses high whiteness and high fineness raw materials in the production process, which can ensure that the materials are not polluted to a certain extent. At present, such zirconia balls are mainly used in the grinding of sand mills.

Ceria Stabilized Zirconia Beads

Ceria stabilized zirconia beads are widely used, especially for grinding materials with high hardness and viscosity. The specific gravity is large, which not only maintains high grinding kinetic energy but also improves grinding efficiency. The surface is smooth, easy to clean, and has little wear on the equipment. High mechanical strength, impact resistance, high-speed operation without fragmentation.

80 zirconium balls

80 zirconium beads are zirconia balls with a zirconia content of nearly 80%, but the performance of this product is more focused on grinding and has been widely used in all walks of life.

Zirconium silicate balls

Its zirconia content is only 65%, so it is often called "65 zirconium". The zirconium silicate beads are made by the advanced process of titration forming in the electrolyte and high-temperature sintering and phasing. There are no pores and cavities in the beads, and the medium density and hardness are suitable for the grinding of medium and low-viscosity slurries.
