Sandblasting Zirconia Beads

Zirconia beads (zirconia balls), also known as zirconia grinding balls, zirconia ceramic balls, zirconia beads, ultra-fine grinding media, zirconia microbeads, zirconia grinding balls, have a pearl-like luster and a smooth working spherical surface. Using micron and sub nano zirconia powder as raw material, yttrium oxide or cerium oxide as a stabilizer, titration or dry bag isostatic pressing into dry type, high-temperature calcination, and phasing process, the shape is spherical, each The technical indicators and performance have reached the international advanced level, and it is the among grinding media. It has extremely high strength and high toughness at room temperature, good wear resistance, high-temperature resistance and corrosion resistance, high rigidity, non-magnetic conductivity, and electrical insulation. When the temperature of zirconia beads is 600°C, the strength, and hardness are al unchanged, the density is 6g per cubic centimeter, and the thermal expansion rate is close to that of metals, so they can be used in conjunction with metals. High specific gravity, providing higher grinding efficiency; Meticulous surrounding structure, ensuring better wear resistance; Smooth working surface, perfect roundness, narrow particle size distribution of ±0.03mm, reducing internal friction of beads and equipment contact parts wear.

Product grinding principle:

Applications:

Zirconia beads use earth yttrium oxide (cerium oxide) as a stabilizer and use raw materials with high whiteness and fineness to ensure that the materials will not be polluted. Meticulous microstructure and smooth working surface reduce the internal friction of beads and improve grinding efficiency.
