ZIRCONIA (YSZ) GRINDING CYLINDERS

202301186082.jpg


◆Product Intrduction
Zirconia Y-TZP cylinder media is made from super material and advanced technical craft and suitable for any kinds of mills such as micro-mill, attritor-mill, vibratory mill and bead mill to grind and disperse effectively and economically the material of electronic slurry, ceramic powder, magnetic material, battery material, rare-earth material, nonmetal ore, painting, dye, ink, calcium, titanium, pesticide, food stuff and medicine etc.


Comparing with other grinding media such as Alumina media, zirconia silicate media, steel media, agate media and glass media, Zirconia Y-TZP grinding media has high density and toughness and super hardness, so it has better grinding efficiencies. The high wear-resistant Zirconia Y-TZP grinding media prevents materials from being contaminated and chemical etching or short service life of the grinder.


These special features make Zirconia Y-TZP grinding media especially suitable for material grinding in important occasion.

 

◆Product Features
Product Features Preventing material from contamination
High grinding efficiency
Suitable for high viscosity, wet grinding and dispersion
So it's tougher and more resistant to wear and deterioration from a long term point of view.
