Zirconia ceramic ball is the most durable grinding ball, high density at 6.05g/cm3.Zirconia ball have the outstanding features such as: high mechanical strength, long durability, high density, excellent wear resistant, ultrahigh hardness, so the zirconium oxide balls is the most ideal grinding ball and increased the grinding efficiency significantly.
Applications of Zirconia Grinding Media is as follows.You can find they can be used in many areas.we can make zirconia beads according to your requirement.
– Iron- and chrome-based magnetic materials (for audio/video recording tapes) and other magnetic materials.
– Electronic-grade ceramics (ferroelectric, piezoelectric, dielectric, capacitors, sensors, etc ), advanced structural ceramics, and other ceramic ingredients.
– Nanostructured and superfine powders.
– Toner materials for photocopiers and laser printers.
– Inks, dyes, paint, and other pigments.
– Pharmaceutical, food, chemical, and textile applications.
– zirconia ball also can be used in Lab milling operations demanding minimized contamination from milling media.
Characteristics of yttrium stabilized zirconia beads:
1. High grinding efficiency: The specific gravity of this kind zirconia beads is 1.6 times that of zirconia silicate beads and 3 times that of glass beads, resulting in higher grinding efficiency under the same conditions.
2. Good fluidity: zirconia balls have good roundness, smooth surface, and lower wear on equipment compared to other grinding media.
3. Impact resistance and low wear: ZrO2 ceramic ball have good toughness and do not crack or peel in high-speed and high concentration machines. Their wear resistance is 50 times that of glass beads and about 5 times that of zirconium silicate beads.
4. Low usage cost: Choosing zirconia ball will definitely bring you a reduction in comprehensive costs such as medium wear, electricity consumption, labor, equipment, etc., and significantly improve product quality.
