Description:

Zirconia Balls are manufactured from dry Yttria Stabilized Zirconia powder by high compaction press. They was sintered at a high temperature to form a Tetragonal Zirconia Polycrystal(Y-TZP) microstructure. The highest bending strenghth and fracture toughness was considered the first choice of grinding media to mill the most sensitive powder or slurry.

Characteristics:

1. Preventing material from contamination because of its extreme low wear rate.

2. High grinding efficiency.

3. Lower total costs due to the long using life.

Cylinder: φ3x3, φ5x5, φ7x7, 10x10, 12x12mm

 Criteria in Selecting Size of Zirconia Grinding Media:

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

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

3.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.

4. 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.
