Zirconia (YSZ) Ceramic

 

Characteristics:
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 grinding solution for a variety of industries.
Advantages of Zirconia Grinding Media:
1)Ultra low wear loss as a result of the transformation-toughening mechanism unique to the yttrium stabilized zirconia(YST) material system.
2)Higher grinding efficiency and reduced grinding time due to the higher density of zirconia (compared with alumina or glass)
3)Most durable grinding material, reducing operational cost in the long run. Wear rate substantially lower than Al2O3, CeO2-ZrO2, and MgO-ZrO2 grinding media.
4)Suitable for high velocity operations and wet grinding operations.
