Zirconia Ceramic Beads
Chemshun zirconia beads including Zirconium silicate beads, Zirconia toughened alumina beads, Ceria-stabilized zirconia beads, Yttria-stabilized zirconia beads.
Chemshun zirconia beads, a kind of ceramic grinding media, havefeatures of good quality, no fracture, stable performance, reliable quality and long service life. They're low comprehensive operating cost which can effectively ensure that the abrasive material is not polluted, and maintain the high purity of the abrasive material. The high density of thezirconia ceramic beads can improve the grinding efficiency. And due to the low wear rate of zirconia mill balls, the stability of the grinding process condition can be effectively ensured. The stability and consistency of the quality of the raw material facilitates process control and management.
The Benefits of Zirconia Beads:
- High crushing strength and fracture durability superior wear resistance which has no any break under high speed impace. They can improve the efficience of grinding and no contamination.
- Smooth surface, good sphericity and low self-loss.
- High density and excellent grinding efficiency for grinding materials down to Nano size.
- Significant cost and waste reduction.
