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.SPHERICAL ZIRCONIA (YSZ) GRINDING MEDIA
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.· Suitable for high velocity operations and wet grinding operations.
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.· Lab milling operations demanding minimized contamination from milling media.
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.· Another important criterion in selecting media size is the gap size between stirring arms and mill walls. Media size should be significantly smaller than the gap size to prevent jamming.
