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.
