Ceramic Grinding Media: Ceramic Grinding Balls, Ceramic Grinding Cylinders
Material: ZrO2, Zirconia Ceramic, Zirconium Oxide, Y-TZP
Ceramic Grinding Media is always used for vertical agitating mills,horizontal scroll ball mills, vibrating ball mills and all kinds of pin type sand mills. Because of the special property, it has high chemical resistance to various paint, ink, dye, pigment.

Property Description of ZrO2 Ceramic
*Use temperatures up to 2400°C
*High density
*Low thermal conductivity (20% that of alumina)
*Chemical inertness
*Resistance to molten metals
*Ionic electrical conduction
*Wear resistance
*High fracture toughness
*High hardness

Typical Uses of ZrO2
1.Precision ball valve balls and seats
2.High density ball and pebble mill grinding media
3.Rollers and guides for metal tube forming
4.Thread and wire guides
5.Hot metal extrusion dies
6.Deep well down-hole valves and seats
7.Powder compacting dies
8.Marine pump seals and shaft guides
9.Oxygen sensors
10.High temperature induction furnace susceptors
11.Fuel cell membranes
12.Electric furnace heaters over 2000°C in oxidizing atmospheres
