Zirconia (ysz) Grinding Media ( Balls)

An Efficient, Longer-Lasting & Virtually Contamination-Free Solution for Ceramic Grinding & Milling

Zirconia (YSZ) grinding media is the most durable and efficient media for ball milling and attrition milling of ceramic materials. Zirconia grinding media provides a virtually contamination-free ball milling solution for a variety of industries.

Advantages of Zirconia Grinding Media

* Ultra low wear loss as a result of the transformation-toughening mechanism unique to the yttria stabilized zirconia (YSZ) material system.

* Higher grinding efficiency and reduced grinding time due to zirconia's higher density (compared with alumina and glass).

* Most durable grinding material, reducing operational cost in the long run.  Wear rate substantially lower than Al₂O₃, CeO₂-ZrO₂, and MgO-ZrO₂ grinding media.

Applications of Zirconia Grinding Media

* 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.

Criteria in Selecting Size of Zirconia Grinding Media

* Larger-sized media are more efficient in breaking up large particles.

* Smaller media are more efficient in milling smaller particles because of higher effective contact area.

* Larger media sizes are favored in many conventional ball mills.  Smaller sizes are more appropriate for attritors.  For example, 5mm media are used in many attrition mill applications, whereas 10-15 mm     may be a good start for a lab ball mill.  For small-media mills, media sizes are typically smaller than 2 mm.
